I genuinely think Mouthwashing fandom is a good example on how real life misogyny is very wired on people brains and influenced how they engage with fictional misogyny.
You have a story about a woman being assaulted and telling a man he trusted but being dismissed because he is friends with the attacker, and people fixate on shipping her with either of those men.
You have a story about how men that downplay their male friends violence, assume neutrality is the safer option, unintentionally help create an environment that's unsafe to vulnerable people, at a risk becoming a victim themselves. And people make it about toxic yaoi.
You have a character kill herself because she didn't want birth the child of her abuser. And people make AUs where she happily keep the baby.
Misogyny isn't just "I hate this women", it's also downplaying their trauma, defending those who caused it, and reducing them to mothers or wives against their wished under this idea of what womanhood is about.
I don't think we can separate fandom misogyny from it's real world influence, not yet.
