性別認同
Gender discrimination is discrimination based on actual or perceived gender identity. Gender identity is "the gender-related identity, appearance, or mannerisms or other gender-related characteristics of an individual, with or without regard to the individual's designated sex at birth". Gender discrimination is theoretically different from sexism. Whereas sexism is prejudice based on biological sex, gender discrimination specifically addresses discrimination towards gender identities, including third gender, genderqueer, and other non-binary identified people. It is especially attributed to how people are treated in the workplace, and banning discrimination on the basis of gender identity and expression has emerged as a subject of contention in the American legal system.
