Really? Larry summers might agree with you, but not many others would. Oh, and by the way, most kids don't learn math and science from their parents. We have a thing in this country called schools that we generally send our kids too so that they can learn math and science.
By the way...correlation does not mean causation. I'd like some evidence that these differences are genetic, and not societal. Don't bother looking, there isn't any.
I know...there are a lot more male lawyers in this country than female lawyers. Even though I grew up without a father figure, I had to struggle a lot because I just couldn't understand the law. I mean, gee whiz, I didn't have a male to teach me opinio juris and other things I would need for law school when I was in middle school.
By the way...since you seem determined to ignore my question about how many kids of gay parents you know, I'm going to assume you don't know any. I know at least 10, all who have turned out fairly normal. Most are very tolerant and open-minded and all are great kids.
Oh, and the great thing about kids with gay parents? None of them are accidents. No teenage pregnancies. The parents all have stable incomes and all of them were expecting to have children and are very happy with that decision.
