If a gay person commits suicide. Is it still called suicide or is it homocide?
I don't think that sounds right at all. Are you saying gay men kill themselves because they are gay?
Yes, they kill themselves because they can't stand the fact that they are gay.
I highly doubt that gay men want to kill themselves because they are gay. Gay people have a lot of pride in who they are and should feel welcomed expressing their true selves. Learning more about what the gay community has done for society I feel would definitely change your outlook on the gay community.
