What does that have to do with the fact that gays have children? There are far more heterosexuals than homosexuals. So it is, hopefully, obvious that the majority of parents in the US will be heterosexual. It is also a fact that many of them (the heterosexuals) will be lousy to really bad parents.
But that does not change the fact that gays are here to stay and they have kids and they raise them. You can condemn the idea all you want to - but it will not change the reality.
The first step to solving a problem is to identify it. The gay lifestyle is not the core of the problem in our society -- it is a symptom. I'm the one who did the graduate thesis on marriage and society, who has the yards-long bibliography; yet posters here seem to believe that if I think gay parenting is a bad idea for the children involved, I can't possibly have given the matter any thought and am simply a bigot. That is pitiable. I've given the matter a ton of thought, research and effort. I've been an employer of gays and an AIDS caregiver. And although I started out believing much as you do, the actual research convinced me otherwise. That is the meaning of education, is it not?
