Gender identity in the context of Sexual discrimination

Gender is the range of social, psychological, cultural, and behavioral aspects of being a man (or boy), woman (or girl), or third gender. Although gender often corresponds to sex, a transgender person may identify with a gender other than their sex assigned at birth. Most cultures use a gender binary, in which gender is divided into two categories, and people are considered part of one or the other; those who are outside these groups may fall under the umbrella term non-binary. Some societies have third genders (and fourth genders, etc.) such as the hijras of South Asia and two-spirit persons native to North America. Most scholars agree that gender is a central characteristic for social organization; this may include social constructs (i.e. gender roles) as well as gender expression.

The word has been used as a synonym for sex, and the balance between these usages has shifted over time. In the mid-20th century, a terminological distinction in modern English (known as the sex and gender distinction) between biological sex and gender began to develop in the academic areas of psychology, sociology, sexology, and feminism. Before the mid-20th century, it was uncommon to use the word gender to refer to anything but grammatical categories. In the West, in the 1970s, feminist theory embraced the concept of a distinction between biological sex and the social construct of gender. The distinction between gender and sex is made by most contemporary social scientists in Western countries, behavioral scientists and biologists, many legal systems and government bodies, and intergovernmental agencies such as the WHO. The experiences of intersex people also testify to the complexity of sex and gender; female, male, and other gender identities are experienced across the many divergences of sexual difference.

Identity is the set of qualities, beliefs, personality traits, appearance, or expressions that characterize a person or a group.

Identity emerges during childhood as children start to comprehend their self-concept, and it remains a consistent aspect throughout different stages of life. Identity is shaped by social and cultural factors and how others perceive and acknowledge one's characteristics. The etymology of the term "identity" from the Latin noun identitas emphasizes an individual's "sameness with others". Identity encompasses various aspects such as occupational, religious, national, ethnic or racial, gender, educational, generational, and political identities, among others.

Heteronormativity is the definition of heterosexuality as the normative human sexuality. It assumes the gender binary (i.e., that there are only two distinct, opposite genders) and that sexual and marital relations are most fitting between people of the opposite sex.

Heteronormativity creates and upholds a social hierarchy based on sexual orientation with the practice and belief that heterosexuality is deemed as the societal norm. A heteronormative view, therefore, involves alignment of biological sex, sexuality, gender identity and gender roles. Heteronormativity has been linked to heterosexism and homophobia, and the effects of societal heteronormativity on lesbian, gay and bisexual individuals have been described as heterosexual or "straight" privilege.

Identity politics is politics based on a particular identity, such as ethnicity, race, nationality, religion, denomination, gender, sexual orientation, social background, political affiliation, caste, age, education, disability, opinion, intelligence, and social class. The term encompasses various often-populist political phenomena and rhetoric, such as governmental migration policies that regulate mobility and opportunity based on identities, left-wing agendas involving intersectional politics or class reductionism, and right-wing nationalist agendas of exclusion of national or ethnic "others".

The term identity politics dates to the late twentieth century, although it had precursors in the writings of individuals such as Mary Wollstonecraft and Frantz Fanon. Many contemporary advocates of identity politics take an intersectional perspective, which they argue accounts for a range of interacting systems of oppression that may affect a person's life and originate from their various identities. To these advocates, identity politics helps center the experiences of those they view as facing systemic oppression so that society can better understand the interplay of different forms of demographic-based oppression and ensure that no one group is disproportionately affected by political actions. Contemporary identity labels—such as people of specific race, ethnicity, sex, gender identity, sexual orientation, age—are not mutually exclusive but are, in many cases, compounded into one when describing hyper-specific groups. An example is that of African-American homosexual women, who can constitute a particular hyper-specific identity class.

Moral universalism (also called moral objectivism) is the meta-ethical position that some system of ethics, or a universal ethic, applies universally, that is, for "all similarly situated individuals", regardless of culture, disability, race, sex, religion, nationality, sexual orientation, gender identity, or any other distinguishing feature. Moral universalism is opposed to moral nihilism and moral relativism. However, not all forms of moral universalism are absolutist, nor are they necessarily value monist; many forms of universalism, such as utilitarianism, are non-absolutist, and some forms, such as that of Isaiah Berlin, may be value pluralist.

In addition to the theories of moral realism, moral universalism includes other cognitivist moral theories, such as the subjectivist ideal observer theory and divine command theory, and also the non-cognitivist moral theory of universal prescriptivism.

Prejudice can be an affective feeling towards a person based on their perceived social group membership. The word is often used to refer to a preconceived (usually unfavourable) evaluation or classification of another person based on that person's perceived personal characteristics, such as sex, gender, gender identity, beliefs, values, social class, friendship, age, disability, religion, sexuality, race, ethnicity, language, nationality, culture, complexion, beauty, height, body weight, occupation, wealth, education, criminality, sport-team affiliation, music tastes or other perceived characteristics.

The word "prejudice" can also refer to unfounded or pigeonholed beliefs and it may apply to "any unreasonable attitude that is unusually resistant to rational influence". Gordon Allport defined prejudice as a "feeling, favorable or unfavorable, toward a person or thing, prior to, or not based on, actual experience". Auestad (2015) defines prejudice as characterized by "symbolic transfer", transfer of a value-laden meaning content onto a socially-formed category and then on to individuals who are taken to belong to that category, resistance to change, and overgeneralization.

Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals.The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin.

Attitudes towards different forms of hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, gender, or religion.

In metaphysics, identity (from Latin: identitas, "sameness") is the relation each thing bears only to itself. The notion of identity gives rise to many philosophical problems, including the identity of indiscernibles (if x and y share all their properties, are they one and the same thing?), and questions about change and personal identity over time (what has to be the case for a person x at one time and a person y at a later time to be one and the same person?). It is important to distinguish between qualitative identity and numerical identity. For example, consider two children with identical bicycles engaged in a race while their mother is watching. The two children have the same bicycle in one sense (qualitative identity) and the same mother in another sense (numerical identity). This article is mainly concerned with numerical identity, which is the stricter notion.

The philosophical concept of identity is distinct from the better-known notion of identity in use in psychology and the social sciences. The philosophical concept concerns a relation, specifically, a relation that x and y stand in if, and only if they are one and the same thing, or identical to each other (i.e. if, and only if x = y). The sociological notion of identity, by contrast, has to do with a person's self-conception, social presentation, and more generally, the aspects of a person that make them unique, or qualitatively different from others (e.g. cultural identity, gender identity, national identity, online identity, and processes of identity formation). Lately, identity has been conceptualized considering humans’ position within the ecological web of life; this combination of sociocultural and ecological identification is known as ecocultural identity.

Social privilege is an advantage or entitlement that benefits individuals belonging to certain groups, often to the detriment of others. Privileged groups can be advantaged based on social class, wealth, education, caste, age, height, skin color, physical fitness, nationality, geographic location, cultural differences, ethnic or racial category, gender, gender identity, neurodiversity, physical disability, sexual orientation, religion, and other differentiating factors. Individuals can be privileged in one area, such as education, and not privileged in another area, such as health. The amount of privilege any individual has may change over time, such as when a person becomes disabled, or when a child becomes a young adult.

The concept of privilege is generally considered to be a theoretical concept used in a variety of subjects and often linked to social inequality. Privilege is also linked to social and cultural forms of power. It began as an academic concept, but has since been invoked more widely, outside of academia. This subject is based on the interactions of different forms of privilege within certain situations. It can be understood as the inverse of social inequality, in that it focuses on how power structures in society aid societally privileged people, as opposed to how those structures oppress others.

Third gender or third sex is an identity recognizing individuals categorized, either by themselves or by society, as neither a man nor a woman. Many gender systems around the world include three or more genders, deriving the concept either from the traditional, historical recognition of such individuals or from its modern development in the LGBTQ community, which can include third gender people as a non-binary identity. The term third is usually understood to mean "other", though some societies use the concept to encompass fourth and fifth genders.

The state of personally identifying as, or being identified by society as, a man, a woman, or other is usually also defined by the individual's gender identity and gender role in the particular culture in which they live.

A transgender (often shortened to trans) person has a gender identity different from that typically associated with the sex they were assigned at birth. The opposite of transgender is cisgender, which describes persons whose gender identity matches their assigned sex.

Many transgender people desire medical assistance to medically transition from one sex to another; those who do may identify as transsexual. Transgender does not have a universally accepted definition, including among researchers; it can function as an umbrella term. The definition given above includes binary trans men and trans women and may also include people who are non-binary or genderqueer. Other related groups include third-gender people, cross-dressers, and drag queens and drag kings; some definitions include these groups as well.

The gender binary (also known as gender binarism) is the classification of gender into two distinct forms of masculine and feminine, whether by social system, cultural belief, or both simultaneously. Most cultures use a gender binary, having two genders (boys/men and girls/women).

In this binary model, gender and sexuality may be assumed by default to align with one's sex assigned at birth. This may include certain expectations of how one dresses themselves, one's behavior, sexual orientation, names or pronouns, which restroom one uses, and other qualities. For example, when a male is born, gender binarism may assume that the male will be masculine in appearance, have masculine character traits and behaviors, as well as having a heterosexual attraction to females. These expectations may reinforce negative attitudes, biases, and discrimination towards people who display expressions of gender variance or nonconformity or those whose gender identity is incongruent with their birth sex.

Non-binary or genderqueer gender identities are those that are outside the male/female gender binary. Non-binary identities often fall under the transgender umbrella since non-binary people typically identify with a gender that is different from the sex assigned to them at birth, although some non-binary people do not consider themselves transgender.

Non-binary people may identify as an intermediate or separate third gender, identify with more than one gender or no gender, or have a fluctuating gender identity. Gender identity is separate from sexual or romantic orientation; non-binary people have various sexual orientations.

Gender expression (or gender presentation) is a person's behavior, mannerisms, interests, and appearance that are associated with gender in a particular cultural context, typically understood in terms of masculinity and femininity. Gender expression is an external display of one's gender identity, through aspects such as clothing, hairstyles, voice, makeup, body language, and behavior.

A person's gender expression may align with traditional gender roles or may be gender nonconforming, incorporating both masculine and feminine traits or neither. It may or may not reflect their gender identity or sex assigned at birth. Gender expression is influenced by sociocultural norms and is distinct from both gender identity and sexual orientation.

While in ordinary speech, the terms sex and gender are often used interchangeably, in contemporary academic literature, the terms often have distinct meanings, especially when referring to people. Sex generally refers to an organism's assigned biological sex, while gender usually refers to either social roles typically associated with the sex of a person (gender role) or personal identification of one's own gender based on their own personal sense of it (gender identity).

Most contemporary social scientists, behavioral scientists and biologists, many legal systems and government bodies and intergovernmental agencies such as the WHO make a distinction between gender and sex. In most individuals, the various biological determinants of sex are congruent, and sex is consistent with the individual's gender identity, but in rare circumstances, an individual's assigned sex and gender do not align, and the person may be transgender.

Sexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term sexology does not generally refer to the non-scientific study of sexuality, such as social criticism.

Sexologists apply tools from several academic fields, such as anthropology, biology, medicine, psychology, epidemiology, sociology, and criminology. Topics of study include sexual development (puberty), sexual orientation, gender identity, sexual relationships, sexual activities, paraphilias, and atypical sexual interests. It also includes the study of sexuality across the lifespan, including child sexuality, puberty, adolescent sexuality, and sexuality among the elderly. Sexology also spans sexuality among those with mental or physical disabilities. The sexological study of sexual dysfunctions and disorders, including erectile dysfunction and anorgasmia, are also mainstays.

Intersex people are those born with any of several sex characteristics, including chromosome patterns, gonads, or genitals that, according to the Office of the United Nations High Commissioner for Human Rights, "do not fit typical binary notions of male or female bodies". The opposite of intersex is endosex, which describes persons born with sex characteristics that are seen as typically male or female at birth.

Sex assignment at birth usually aligns with a child's external genitalia. The number of births with ambiguous genitals is in the range of 1:4,500–1:2,000 (0.02%–0.05%). Other conditions involve the development of atypical chromosomes, gonads, or hormones. The portion of the population that is intersex has been reported differently depending on which definition of intersex is used and which conditions are included. Estimates often range from 0.018% (one in 5,500 births) to 1.7%. The difference centers on whether conditions in which chromosomal sex matches a phenotypic sex which is clearly identifiable as male or female, such as late onset congenital adrenal hyperplasia (1.5 percentage points) and Klinefelter syndrome, should be counted as intersex. Whether intersex or not, people may be assigned and raised as a girl or boy but then identify with another gender later in life, while most continue to identify with their assigned sex.

Bisexuality is romantic attraction, sexual attraction, or sexual behavior toward both males and females. It may also be defined as the attraction to more than one gender, to people of both the same and different gender, or the attraction to people regardless of their sex or gender identity (pansexuality).

The term bisexuality is mainly used for people who experience both heterosexual and homosexual attraction. Bisexuality is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality, all of which exist on the heterosexual–homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual.
