The real question isn't whether it's genetic or not, but whether it's so hard-wired in people's brains from an early age that it can't be changed. Given how many homosexuals have fought their urges and tried (and failed) to go straight with marriages and therapy, it seems to me that homosexual desire isn't something that's a choice or can be made to go away. The only "choice" is whether people act on those desires or not.
I don’t have much to say regarding your post. I think we all grasp for answers to understand this. I would probably be less supportive of the hard-wired concept. Hey, that’s just MO.
