"But once gay parenting is open to the same elements of society that the heterosexual population reflect, including poor, uneducated, from broken homes, then it is reasonable to assume many of the same societal ailments which plague the "breeders" in marriage will also plague the "gays"."

A lot of breeders become that way because of laziness--remember, all it takes for a hetero to become one is to not use birth control. Simple biology suggests that that would be impossible for a gay couple--to have lots of children requires the payment of money for medical or adoption procedures to circumvent biology. Random child production cannot happen with a gay couple.

That's not to say a gay couple can't be disfunctional, or that a child of a disfunctional gay marriage would not hate gays as a result. But it's not inevitable, either, and the exact same process can happen with a straight couple. And if the child knows of other, happier, gay families, that blame is less likely to happen for the same reasons people seldom blame their parents' straightness.
