Sure incest does for obvious reasons. If children can be viewed as legitimate future sex objects by a parent or sibling in a family, they can be viewed as current ones.You are mistaken in the homophobia. I'm not suggesting that homosexuality encourages pedophilia. I'm rejecting your suggestion that incest does any more than homosexuality does. Parents abusing their children isn't a product of their incestuous desire, but the incest is a result of their abusive desire.
