I'd think you'd want to read that book. You seem to put a lot of stock in the findings of one scientist -- here's a chance to get a look at a broad range of the research in his field and see how his methods stack up. But hey, you accept whatever terms you want, I'm not going to nag you about it. But one day, you will read that book, if out of curiosity more than anything else.
As far as blank slates go, well, I have mechanical aptitude -- which neither my mother nor father have. I can act -- which neither of my parents could do. I can't play any musical instrument, although both my parents had natural musical talent. I read constantly although neither of my parents ever read anything more complicated than a newspaper once they got out of high school. So I dunno -- whatever my behavior is I didn't inherit it from them. I wouldn't say we're entirely blank, but neither would I suggest that our traits are engraved in our genes, whether along gender lines or what. At most, we might have an inclination toward certain things, but anything else we have to pick up on our own.
