Growing up, I knew two young boys, nice kids, who are homosexual. There were indications even as young as primary school that they were predisposed to homosexuality. In high school, having no interest in girls in the traditional sense, one took my sister or her friend, as buddies, to all school functions requiring a date. There was no indication of sexual exploitation as children, and none has ever been told to us. My sister still keeps in contact with both. From very early on we somehow knew something was "different."
I remember reading an article regarding a limited study of the autopsies of homosexual AIDS victims. I believe the autopsies did reveal some difference in brains of the homosexual men. Regardless, opposing gay right's has become an issue of so-called morality for the right, but there is absolutely nothing moral or virtuous about vilifying a minority group. When it is done purely for political purposes, it is particularly deplorable.
