To commit a homosexual act one would need to be attracted to the same gender. So where is the choice in that? That's what this thread is about.
If that is so, then how do you explain ancient Greece, where pederasty was the norm? Not to mention what we call homosexuality likewise being, if hardly the norm, then at least far, far more common and mainstream in ancient Greece than today? And what about the "gay for pay", otherwise heterosexual men who perform homosexual acts in pornographic films and whatnot? Do not all of things require sexual attractions that you would insist are not chosen and, indeed, beyond choice?
That said, and for the record, I do not believe sexual orientation is typically "chosen". I believe perversity can have so profound an effect on one's sexuality that all sorts of attractions can develop and adhere, include homosexuality, but I think that's rather uncommon. For the vast majority one's orientation develops during puberty as a result of both biological and environmental factors. Mostly environmental.
But the fact remains that you're not showing much of an interest in the reality of homosexual orientation, but seem to be instead defending the rather ignorant, albeit conveniently politically correct, tripe.
