Before we discuss any of that, because all of it is based off an assumption, do you have evidence that a gay brain causes homosexuality? (i.e. we look at a brain and we can tell they're going to be gay, bar none?)
Yes, information is processed differently at a electrochemical level, but that doesn't mean some who has a gay brain is automatically gay. At least that's the stance until someone can prove that a gay brain => gay human, as of right now, there's no evidence we're born gay. Which brings back the main point of evidence.
Schizophrenic brains are different than 'normal' brains, but people with larger than normal ventricles in their brains have never displayed symptoms. (a basic predisposition study that's based on an actual disorder rather than sexuality and thus it's been studies more extensively) This is why scientists are so careful not to say people are born schizophrenics. I bet you can not find
any reputable article where a researcher will tell you people are born gay, no other factors are involved. This is absolutely wrong because there's no evidence to support it, all we have is data on how the brain looks different, and again, I stress it does not imply causality.
Oh, and I did read the entire thing before replying and ignoring it, but statements such as:
By that i mean a gay brain is a gay brain and the most hormonal changes could do is alter a gay brain but it can't turn it into a straight one
and
Sexuality does not adapt in youth, it develops
and
If sexuality could adapt than there would be no gay people in areas where gays are persecuted because there is clearly nothing to be gained from having to go through what they will be forced to endure.
Imply that sexuality is predetermined instead of predispositioned, which I'm getting tired of saying is not proven. And for the last quote, my reply was in my last reply:
2. Predisposition does not mean there's something wired in you that will make you gay unless environment and social factors come into play.
Of course predisposition is on a scale, so the gay people in that environment would be 'more' predispositioned by their bio (in terms of brains, a male would have more definite straight-female features) so while most are going to be straight, some of the gay males would want to rebel by becoming gay. (of course, I'm making shit up now, but you can see there exists explanations as plausible as your own)
As for the biology thing, nerve connections change a lot during youth and that could have a huge influence. Kid plays chess, new nerve connections favoring logic form. Kid walks in on mommy and daddy and decides that's disgusting, new nerve ending favoring homosexuality form. (The first one is proved, the second one I made up but is plausible and I'd even say likely. Of course you can't really test the second one...)
