On average, males have 7x more grey matter than females, and females have 10x more white matter than males, this leads to several behavioural differences and can be seen in frmi scanners. MTF brains very closely resemble a female brain and vice versa.

Neural pathways also differ noticeably, with females having far more links crossing from their right and left brain

This makes men, on average better at motor skills and logical reasoning, whilst making women better at emotional understanding and words.

... and then there’s hormones which also differ between men and women pretty noticeably.

It’s not helpful to pretend gender doesn’t exist. It does. And some male-borns have brains which resemble the typical female brains and vice versa. It’s something that will always happen.

This doesn’t really have anything to do with the OP though. Of course babies have a sex. The labour woman was daft saying that. She probably meant babies don’t have a gender. She would’ve been close to correct.

Seems it depends which article/study you read Withano, dont tell me I'm "pretending" anything

Have you read any articles or studies which suggest biologically influenced gendered behaviour does not exist?

This is a good article

Rippon is basically considered a twat amongst her peers for ignoring science tbf - genuinely. You’ve read an article about a book that an idiot wrote. Rippons work is largely dismissed by peers.
