I might have gay friends, I don't know. I don't exactly go up to my friends and say "HELLO ARE YOU GAY BECAUSE IF YOU ARE I'M TOTALLY OKAY WITH IT REALLY". I just figure that if they think it's important, they'll mention it themselves.
I actually am/would be okay with it, by the way. Seeing as, what, 10% of the population is homosexual, and the phenomenon (sorry if the word choice offends in some way) is not limited to humans, I don't think it's "unnatural" per se, just somewhat different and not really productive to procreation. I prefer not to discriminate against anybody for anything that is not their choice. Seeing as sexual orientation is hard-coded into people from birth, I do not consider it a choice or even necessarily a bad thing.
tl;dr Don't know, don't care.
