The anti-gender movement is a global right-wing social movement in opposition to concepts it refers to as "gender ideology" or "gender theory". These terms are loosely defined, and encompass a range of subjects related to feminism and LGBTQ rights, as well as progressivism in general. The movement has drawn support from right-wing populist groups, religious conservative organizations, social conservatives, and the far-right worldwide. It views advancement in gender equality and gender and sexual diversity as a threat to traditional family values, religious beliefs, and established social norms.
The movement has been criticized for encouraging discrimination, undermining human rights protections, and promoting misinformation and rhetoric against LGBTQ people. The notion of a pervasive and institutionalized "gender ideology" has been described as a moral panic and conspiracy theory.
