My thought on IF drugs and disease were higher in gay-centric is because a large part of society rejects them which leads them down a bad path. Me, believing Nature in the whole Nature V Nurture feel that there is nothing they can do about their sexual orientation just like you can't about yours. So constantly being rejected by friends, family, co-workers, and even strangers leads you down a dark road.
If you're like me you like to talk to things. I'm Gary Busey!!
