Discrimination against gay men
Discrimination against gay men, sometimes called gayphobia, is a form of homophobic prejudice, hatred, or bias specifically directed toward gay men, male homosexuality, or men who are perceived to be gay. This discrimination is closely related to femmephobia, which is the dislike of, or hostility toward, individuals who present as feminine, including gay and effeminate men.
