I think being being black and gay (especially in the south) is somewhat unfortunate because of cultural differences between the races. Certain people may consider you to be "insecure" and "whiny" when you bring up a topic like this, but I think it's a legitimate discussion.
1. To be black and gay is very different than to be white (or any other race for that matter) and gay. Homosexuality is still not nearly as accepted in the african american community as it is in others. African Americans, particularly older generations, tend to view homosexuality as 'evil' and 'sinful.' And of course there are people of other races who may feel the same way, but African Americans as a whole still tend to ostracize homosexuals.
2. Such treatment leads to the "Down Low" phenomenon where black men outwardly live heterosexual lives but secretly practice homosexuality because they fear being ostracized from their community. It's also a known fact that there are way more closeted black men because of the african american community's inability to accept homosexuality. As a matter of fact, this is part of the reason why I'm not totally out.
3. So if you're black and you're gay...what's a guy to do? The number of black guys who are out is disproportionately smaller than the numbers of white guys who are out...so it makes it harder for us black guys to stick to our own kind. I'm not justifying what some consider the whiny, "Why don't white guys like me?" but I just wanted to put it all in perspective. It's not like there's a huge selection of black gay men out there who wouldn't mind being seen in public with another man.
In the end, race shouldn't matter. But it does to many and that sucks. But that's life. Besides, I don't want my race to be the deciding factor in why any guy would date or not date me. If I'm attracted to a guy, I'm attracted more to his mind than his skin color...and I know there are others out there who feel the same way.
