I was going to let that other post go - until I saw yours I supposed most everyone would see how silly it was. Far from pointing out flaws, lonestar's post completely misses the point. In the first place, since virtually all children are raised by heterosexuals, it's completely unsuprising that most homosexuals are raised by heterosexuals.
But where the post goes really astray is by implying the concern is that children raised by homosexuals will become homosexuals themselves when the woory is actually that the children will suffer from not having a mother and a father present, that the nonstandard home environment will hurt them. Now that may be wrong in the present case, but it's not obviously wrong and should therefore not be dismissed out of hand.
You may worry, but there is no evidence that two loving gay parents in a stable relationship damage children whom they raise. I know one such couple, who adopted two kids, out of a foster home, and they are marvelous parents. The kids are thriving. I have seen it with my own two little beady eyes. There is a rigorous screening process for such adoptions, at least in Orange County, and the applicants must go through a 100 hour class first.
