in the context of gender dysphoria and transsexualism the issue becomes even more complicated when you account for the fact that people have different motivations for wanting to change their perceived gender. some may wish to achieve a full social and physiological transition while others are content with just being treated as women by society without extensive physical modification. there is a lot of conflict within the trans movement regarding whether or not to recognize anything short of total transition as legitimate, because it weakens the "trans is an immutable trait we cant help but live with" position in favor of the "trans is a choice" position.
i read a post the other day from a self admitted autogynophile (a man who has a paraphilia for being treated like a woman) that was interesting
ok i have to break this down to the nature of things and how they're defined before i continue.
there are effeminate people and there are masculine people and there are people that don't really fit either. the words effeminate and masculine are just categories for behavior that one sex exhibits more than the other. some of these behaviors are deeply influenced by biology, like maternal instincts or aggression. others are social and can vary depending on the culture.
biological example:
men are more aggressive than women and aggression is mainly a consequence of testosterone.
social example:
it is effeminate to cry among almost all societies.
the line between social and biological is blurred, obviously because biology effects everything we do.
a brain is male if it belongs to a biological male. a brain is female if it belongs to a biological female.
men have more brain mass on average (because they have bigger skulls), but a woman with an abnormally heavy brain would not have a "man brain" despite mass being the main physiological differentiation (to a coroner).
a biological male may exhibit many feminine traits, either due to culture or some kind of biological abnormality, but that does not mean that person would have a "female brain" in any sense, especially when all behaviors exhibited are well within the range of "all behaviors humans do in general."
so no. a male cannot have a female brain because the definition of female brain is simply "brain belonging to a biological female".
@wishgranter14 rly depends on the issue. maybe take a pic of the maintenance history of the car and ask your mechanic which one costed more per year of use
