Transwomen have female brains 🤡

Okay, so i'm tired of people telling me this bullshit that transwomen think like "cis" women or have female brains. Do you know some articles about that?

Whenever a TRA starts spouting off about the lady brain all I can think of is how some racist whites used to claim that other races had different brain sizes, and therefore were less intelligent.

Even if it is proven by science, so are the eggs in my ovaries. If that doesn't make me a female, neither does your dumb brain scan. You're just trying to change one "arbitrary" sex characteristic for another.

The last thing most trans people actually want is for transitioning to come with brain structure requirements. They know that would really whittle the trans community down quite a bit, and there's power in numbers.

Someone else mentioned Gina Rippon, so I thought this interview in which she mentions how she's asked by trans people to "prove" their brains are of the opposite sex (which is impossible according to her) might interest you: https://time.com/5669513/gina-rippon-interview-gender-and-our-brains/

Of all the TRAs arguments, this one is the craziest imo. A vagina and uterus don't prove you're a woman, and a penis doesn't prove you're a man. So the most visibly telling body parts don't indicate you're your sex. But the brain, which has no distinctive differences based on sex, somehow can? That's just crazytown. And by their own argument, isn't it transphobic to claim a woman's brain only belongs to women? Isn't that transphobic against an AMAB who identifies as a woman but unfortunately was born with a man's brain? And omg wouldn't someone please think of the enbies!

It's all such nonsense. Their arguments turn on themselves.
