But that sort of criminal-sociopathic behavior is hardly unique to gay parents. Remember that woman in Maine just a couple of weeks ago who was caught running live webcasts of herself sexually assaulting her preschool-aged children (and she had 4, from 18 months to 5 years). There are actually quite a lot of heterosexual parents using their children to make money via porn and/or prostitution — many seem to be doing it to support a drug habit.
Percentage wise, a homoosexual male is something like 70% more likely to molest a little boy or underage boy. WHY? I think because most homosexuals have themselves been molested as children.
You cite moral failing to rationalize acceptance of moral failing.
