The study asked parents from screwed-up households if they'd ever had a homosexual relationship. It did not get involved with children from stable homosexual hosueholds, of which there are many (including mine). The results show that if one of the parents from a broken home has a homsexual relationship, that it doesn't help the kids, who are already going to have difficulties because they are from a broken home.
And as far as any of you judgemental imbeciles who are going to claim that there are no stable homosexual households, you don't know that. You haven't been to my house.
