How do you then explain the ancient Egyptians pre-4th C BCE where women conducted business and legal transactions and men stayed home and did the weaving? How do you explain the Na of China, where the culture is completely matrilineal and women do all the farming. There are no "father" or "husband" roles. Everyone lives in the home of their mother or grandmother and there is no such thing as formal marriage. Boys and men help to raise the children of their sisters and nieces, and are very involved in doing so.
There is no reputable scientific evidence that the minor differences in brains indicates any difference in aptitudes, abilities, or anything else. Anything that claims there is is junk science.
"What modern neuroscience tells us is this: The idea of the male brain and the female brain suggests that each is a characteristically homogenous thing and that whoever has got a male brain, say, will have the same kind of aptitudes, preferences and personalities as everyone else with that ‘type’ of brain. We now know that is not the case. We are at the point where we need to say, ‘Forget the male and female brain; it’s a distraction, it’s inaccurate.’ It’s possibly harmful, too, because it’s used as a hook to say, well, there’s no point girls doing science because they haven’t got a science brain, or boys shouldn’t be emotional or should want to lead.”
Besides the science that says so, there is also the obvious fact that there are female physicists, that the first coders were women, that men can be great therapists, and teachers, and nurses. How does one begin to explain that away using this junk science. It's just silly...
I’ve already said this to you several times, but I’ll say it once before before bugging out — patriarchy began less than 10k years ago. Before that we had egalitarian cultures that were mostly matrilineal (because who fathered a child wasn’t that important in societies where everyone took care of everyone else). It’s only in the past few thousand years that men have controlled women, that there were different laws for women, where they didn’t have full citizenship, etc. It’s brand new — for only 3% of human history. And not only in different time periods, but in different cultures today, we see other social systems than what we have now in the West. That’s how we know it’s a social system and not “nature” — because it’s not universal. I could link you dozens of stories about this because this is my field, but again, I don’t anticipate that you can use your brain on this topic because you are so deeply in your emotions about it, so I won’t bother.
