I can't assume to speak for him, but I THINK the point he is trying to make is that at one time we considered homosexuality to be in the same boat as pedophilia, and now it has become acceptable. Might the same thing happen with pedophilia if we are turning a blind eye to it in our external pursuits?
Kind of a ridiculous statement or assumption. Pedophilia, rape, etc.... has nothing to do with gay or straight.
