All the differences are clearly the result of socialization or hormones

Those contribute.

I don't think it's known how much genetics and how much hormones contribute to the differences in the brains of males and females.

Your claim that "No one is born with them" would be a 0% contribution by genetics, which is implausible.

Of course you can say people are born with "masculine" and "feminine" brains, but that's circular logic

No. Some of the differences are in the sizes of different structures, and can be measured objectively post-mortem.

Yeah, post-puberty. Even then they don't know many real patterns. They just say "women are more emotional, so having larger emotional centers is a feminine trait".

There's physical differences in the brain from birth. Easiest to measure is size.

And I already explained to you how size is only an indirect correlation. It's caused by other factors that are affected by sex, such as height.

You'll notice that kids are much less stereotypical. Even since infancy they've picked up on gender norms, but it takes long enough that you can see it progress. Kids will play with either gender, but when they get older they'll only hang out with their own gender. Kids begrudgingly follow gender roles because their parents want them to; but by the time they're teenagers it's part of their identity. Kids treat each other the same; grown ups have a whole bunch of double standards based around gender. You can literally see the brainwashing progress over time.

You're mistaken about that. The skull in males, even at birth, is independently larger, even correcting for factors such as height.

There are cultural differences too. But if transexualism can be cultural, which I question, it certainly isn't always. Their brains can be physically more similar to the other gender from the one assigned at birth.

Any differences detected are the result of hormones and do not exist in children. That doesn't mean there aren't any, but we have no evidence.
