Why is something that obviously should well be evolutionarily wiped out (if it is indeed due to genes/people can't help it) not, by now?
(Corollary question if you say "there is no evolution, it's intelligent design" - ok then what the heck purpose would homosexuality serve in this design? Honest question, I'm not being a smartass.)
Edit - PS you know you're over some kind of target if an OP gets downpoots.
I remember learning that in ancient Greece, it was considered healthy for a young man to have a homosexual experience with an older man before he got married. A normal part of his development.
EVIDENTLY
Lots of cultures do this ....TODAY Afghanistan is the most recent example
