I hate the natural v. unnatural and choice v. not a choice arguments for loveuality. If I choose to forget men and/or women, I shouldn't be treated any differently in non-loveual situations based on what I do in private.
Doesn't matter if you're "against gays" or "for gays", just treat people like loving people. The world would be a better place if humanity could understand we're all just sitting on a wet rock hurling through space and we aren't getting out alive, and that's all that matters.
