I might ask you the question of why you assume that a gay man is going to have sex with a child? If you are straight,, are you going to try to have sex with every feamale child you see? Do you assume Gay equals pedophile?
I do not assume that.
I am straight and I don't want to have sex with any female child.
I do not assume that gay equals pedophile.
I recognize that most pedophiles self-identify as heterosexual. I also recognize that a small subset of all people, heterosexual and homosexual, are pedophiles.
Even though I am not interested in little girls, I understand that it would be inappropriate for me to spend the weekend out in the woods with a troop of little girls. Not because of me being a threat, but because no heterosexual man should be in that position.
