The concept of a female brain relies completely on deeply regressive stereotypes of masculinity and femininity, @Toffeefudgecaramel. Liking things which were thought typically feminine - pink, skirts, frills, make up, long hair etc etc - must mean you have a female brain. And someone who has short hair, wears trousers, eschews make up and enjoys sports. must be a man.
These are toxic stereotypes that we have fought for decades to escape - and I thought we had achieved it - women could play rugby, wear nothing but jeans, never use a lick of make up, and no-one doubted that they were female - until the TRAs started saying that not only do these rigid gender stereotypes exist, but anyone not conforming to the stereotype for their sex must be trans.
I firmly believe that a woman is someone with female biology and any personality/character, not someone with any biology and a ‘feminine’ personality/character.
The notion that a male sexed individual can have a female brain, is nonsense. His brain, like every other cell in his body, is male.
