Even if they're right about the differences at either end. We can't make group judgements, we have to make individual ones. There's an example to me of the problem with this idea of immutable brain-based gender differences are people who are multiple personalities. As we know, children who have been very sadistically abused over the long-term are able to dissociate, some of them are able to dissociate as a way of surviving and inventing someone to whom this doesn't happen. And so therefore, they invent within themselves different personalities who have life histories of their own.
Many people invent an opposite gender personality as well.
Say a little boy who his being sexually abused by a man, and this is obviously unacceptable to him socially, will invent a female person to whom it is happening. Or a girl will invent a male person who embodies her anger and so on. Now what's interesting about this is when the person changes from one gender to the next, the brain pattern changes. So all the right-left brain, you know all this stuff can change in seconds, in the same person. So, you know, that tells me that it's a circle, culture changes, biology, so on but that it certainly can intervention at a cultural level can change that behavior.
