@lxo @taylan @oddtail @light @quasi @Gnomeshatecheese What's a masculine brain? I know that both sexes have brains, but how would you define a masculine or feminine one?
As for overlap; there are plenty of ways in which attributes of men and women overlap eg height, weight, strength, speed etc, but a physically strong woman isn't a man any more than a slow-running man is a woman; nor do they get to choose based on these outcomes or their feelings.
People can feel whatever they like, but this has no bearing on reality.
