I've met snake-handlers who at least don't consider themselves opposed to it.
I was first going to ask where one goes to meet snake-handlers, but then I realized something even crazier: you've discussed homosexuality with snake-handlers!
...Did this conversation occur while they were handling their snake?!
With a guy who came in to talk to an anthropology class that I was in, whom I then sought out at his church when passing through the area on a trip to the South earlier this year. He presumably was not even remotely representative of snake-handlers (in that he was friends with an anthropology professor, for example), but he was practicing.
It wasn't a discussion of homosexuality per se; we asked him where he and his church stood on 'the issues' in general and he named that as one that people are sometimes surprised to learn this particular congregation at least isn't too big on opposing.
