Sure, but it was a post in another forum that got me thinking...The post said if we just let gays be from the start, given they can't reproduce then they would have dissapeared long time back. The implication being had gay ppl not been forced to conform to society and have children that it would not have been passed on.But if you look at history, gays prolly, in this country were left pretty much to themselves. As is the same elsewhere before the advent of religous thinking that condemned it. Yet here they are today and very likely will be there tomorrow as well.There is nothing conclusive, as yet in science that shows it can be inherited or whether its even inherited in the first place. As far as science goes we do not understand why it even happens. We don't call it a disorder because enough evidence shows these ppl are very much normal in other aspects. The only difference being their sexual preference.Sexual prefernces are far too powerful to be driven by fads, they are involuntary compulsions. The goal of all life is to propagate itself and the mechanisms to do so are prolly defined fairly early on. Therefore that homosexuals do exist must imply it confers some sort of evolutionary advantage to the species. And if so maybe they have existed nearly as close to day one of the human species.
