I think femininity probably has it's own associate brain damage too, yes. Different, but probably less extensive due to the demands of feminine people to understand the other. Although quite debilitating in important ways. Same for non-white folks. I am more reluctant to speculate about those things because of their history as popular notions ("women and blacks are retarded"), and the fact that I have no direct experience of it. I experience my own developmental delays all the time and I'm a white man.

And I agree with you there are many negatives to manhood and masculinity, many positives to womanhood. I don't see that as contradicting my theory.
