Discourage it, ridicule it, not celebrate it.
HIV/AIDS wasn’t an accident. It is nature’s way of dealing with deviant promiscuity. Keep giving them the Ok’s and pats on the back and when the next wave hits, watch out.
When I was in high school last century, 1959-1963, I didn't know any openly queers. There was one guy in our class who had effeminate mannerisms but he went to the dances, proms etc with a girl.
He's living in Indianapolis now with his "husband" but at least he had the good sense to keep his mouth shut about it in high school. By the way, he was an all around likable guy and probably still is, except for that perversion thing he's got going, I haven't seen him since high school, his sister told me all this "news" a few years back.
He also managed to keep this information from his religious and elderly mother, who is now deceased. Kudos to him for that much.
