it's not misandry because women being punished for being masculine is not born of a hatred of men, it's born of a hatred of women trying to embody men, because it's a position "above them" and they should stay in their place. the idea is women should be passive and pretty, any woman that tries to be strong is seen as gross, unnatural, annoying, tarnished.
it's not something that really stands out too much nowadays but pay a little more attention and you'll see it here and there.
the way people talk about women who are *actually* masculine, the way people talk about FtMs as though they're silly little girls trying to reach a position too far above them, the way people talk about women who get breast reductions, women who try to be funny, women who sleep around, women who tell crude jokes.
these are all things most people think it's fine for men to do but when a woman does it it's met with disgust and annoyance.
it's the same reason why men being punished for feminity isn't misandry, it's not a hatred of men, it's a hatred of men trying to embody women because thats a position that is beneath them.
