Well, you may not know this but you inadvertently just stated reasons against gay child adoption and single parents. A father and mother each provide different things to their children both different, but both necessary for raising a well adjusted child. While I believe this is absolutely true I don't believe it applies to the school system as you wrote above. An example is that I am very poor at spelling. My older son is very good at spelling. Many autistic kids, while not having super memories, have better memories than normal children in certain areas because of the way they think. If your theory were correct my son would have picked up on my weak area (spelling) and would be a poor speller too. But look, I really don't know what's completely best. Some children do very well in school with all the teachers and social interactions. But for other children school can be hell. If your popular, great. If not and you are picked on and bullied it's not such a great life experience. So I will say it depends on the child and the circumstances. I can only say that in our case and with our children I think home schooling is the best for them.
