Question! What is the basis for your claim homosexuals hate/disparage people with red hair? I don’t like homosexual behavior and have seen such close up but I never associated such behavior with a red hair dislike.
Within the homosexual community, red-head men are referred to as ‘gingers.’ Gingerism has been a part of the homosexual community for a long time. Gingers have been stereotyped as slovenly, untrustworthy, promiscuious and prone to cheating, bad tempered, mentally unstable, ‘soul-less’ outcasts, not suitable for a stable relationship, etc etc. Basically all the negative stereotypes that used to be levied against red-headed women.
That this negative stereotype and gingerism is still very much practiced in the homosexual community is evidenced by the Dec 2013 release of a film aimed at the gay community, with a focus on “dismantling the stigma” surrounding redheaded gays.
