We tend to use bitch for women and bastard for men. I don't think it's misandrist to call a man a bastard so it's not misogynist to call a nasty woman a bitch.
Of course it's not misandrist because a bastard was born from a woman that was a "slut" and got pregnant from a man she did not wed. It's not misandrist because it's another misogynist slur if you actually think about it.
Bitch is very much still sexist as it dehumanises women to a dog. A man can be a bitch because calling a man an inferior woman is still an insult, again misogynist.
Cunt, karen, attention whore, drama queen, bitch, slut, son of a bitch/whore, nancy boy, old hag, cow, fish, witch, terf, you throw like a girl, chick, douche (thing to clean a vagina) ...
The list is endless. And even insults for men are referring to women and demeaning them.
It's just gross and continuing to using slurs feels so wrong as a woman. On rare occasions i feel a "bitch" is in order but its so rare. I really don't want this so normalised because it affects us all.
