Homophobia encompasses a range of negative attitudes and feelings toward homosexuality or people who identify or are perceived as being lesbian, gay or bisexual. It has been defined as contempt, prejudice, aversion, hatred, or antipathy, may be based on irrational fear and may sometimes be attributed to religious beliefs. Homophobia is observable in critical and hostile behavior such as discrimination and violence on the basis of sexual orientations that are non-heterosexual.

Recognized types of homophobia include institutionalized homophobia, e.g. religious homophobia and state-sponsored homophobia, and internalized homophobia, experienced by people who have same-sex attractions, regardless of how they identify. According to 2010 Hate Crimes Statistics released by the FBI National Press Office, 19.3 percent of hate crimes across the United States "were motivated by a sexual orientation bias." Moreover, a Southern Poverty Law Center 2010 Intelligence Report extrapolating data from FBI national hate crime statistics from 1995 to 2008, found that LGBTQ people were "far more likely than any other minority group in the United States to be victimized by violent hate crime."

The Federation for American Immigration Reform (FAIR) is a nonprofit, anti-immigration organization in the United States. The group publishes position papers, organizes events, and runs campaigns in order to advocate for changes in U.S. immigration policy. The Southern Poverty Law Center classifies FAIR as a hate group with ties to white supremacist groups.

FAIR was founded in 1979 by Michigan surgeon and white nationalist John Tanton. Other co-founders include Otis Graham and former Gulf Oil chief executive officer Sydney Swensrud. It is headquartered in Washington, D.C.

Christian supremacy refers to both the belief that Christianity is superior to other religions and a form of identity politics that asserts that Christians are superior to others and are, therefore, better suited to rule. Christian supremacy overlaps with—and can be considered a core tenet of—Christian nationalism. The New Apostolic Reformation, a dominionist political movement, is described by The Washington Post and scholar Bradley Onishi as promoting Christian supremacy through a mix of hard-right politics and supposed prophecy. Joseph Wiinikka-Lydon of the Southern Poverty Law Center and religion scholar Matthew D. Taylor point to the Seven Mountain Mandate as the plan for Christian dominance and supremacy.

Garrett James Hardin (April 21, 1915 – September 14, 2003) was an American ecologist and microbiologist. He focused his career on the issue of human overpopulation, and is best known for his exposition of the tragedy of the commons in a 1968 paper of the same title in Science, which called attention to "the damage that innocent actions by individuals can inflict on the environment". He is also known for Hardin's First Law of Human Ecology: "We can never do merely one thing. Any intrusion into nature has numerous effects, many of which are unpredictable."

Hardin held hardline anti-immigrant positions as well as positions on race and eugenics that have led multiple sources to label him a white nationalist. The Southern Poverty Law Center described his publications as "frank in their racism and quasi-fascist ethnonationalism".

Paul Edward Gottfried (born November 21, 1941) is an American paleoconservative political philosopher, historian, and writer. He is a former Professor of Humanities at Elizabethtown College in Pennsylvania. He is editor-in-chief of the paleoconservative magazine Chronicles. He is an associated scholar at the Mises Institute, a libertarian think tank, and the US correspondent of Nouvelle École, a Nouvelle Droite journal.

Gottfried helped coin the terms paleoconservative in 1986 and alternative right (with Richard Spencer) in 2008. The Southern Poverty Law Center (SPLC) has described him as a "far-right thinker" and characterizes the H.L. Mencken Club, which he founded, as a white nationalist group. Although noted for working with far-right and alt-right groups and figures, he has said that he does "not want to be in the same camp with white nationalists" or associated with pro-Nazis, "as somebody whose family barely escaped from the Nazis in the '30s".
