Out of curiosity, does your belief system lead you to the conclusion that all gay people will go to hell unless they repent of being gay?
For real, not trying to flame you or anything, I'm just trying to understand your views better.
Personally, I think the biggest problem with the Christian doctrine (as I know it) is that it concludes that homosexuality is a moral issue, when it's clearly not. I know one gay couple that's been together longer than I've been alive, and I don't see anything immoral in that.
Last thing, if you're not gay and a gay dude its on you, just be stoked that someone thinks you're the shit. Just tell them you don't swing that way and take pleasure in knowing that you could have a sausage fest if you so desired. Pop up your collar, put on some orange tanning sauce, look in the mirror and say "I'm so gnarballs that men want to fuck me."
