Oh, this American sexism nonsense again. Why, btw, no one is complaining that women have no predispositions for "autistic traits" ("being a male is to have some slight form of autism", like they said) and that girls with Asperger's, like, supposedly, Ayn Rand, is one for a billion. Why no one is protesting against the facts that men are much worse in caring for babies, because they have not enough "non-verbal communication abilities" to stay in a "continuous non-verbal rapport" with a toddler 24 hours a day? Why just not accept the fact that women are evolved to be better at some tasks at the expense of the other (and so are men)? So-called gender equality is a nonsensical "mental" concept (like any other "equality" nonsense which goes against the nature - genes is the very vehicle of inequality), given that the whole "evolutionary reasoning" behind a gender is necessary diversification of functions and abilities.
