Children from Gay couples performed worst in academic and social caregories
A 1996 study by an Australian sociologist compared children raised by heterosexual married couples, heterosexual cohabiting couples, and homosexual cohabiting couples.
It found that the children of heterosexual married couples did the best, and children of homosexual couples the worst, in nine of the thirteen academic and social categories measured.
