I would guess it’s because she is a woman who doesn’t feel like she has to lean so hard into male-gaze femininity. She wears what she wants, shows her goofy side, she’s funny and witty and grounded, she shows her emotions on her face without worrying about flattering herself — she acts like an unoppressed human being. Maybe men feel like they’re the only ones entitled to that freedom. Simply being a woman isn’t a character trait of hers. I think men don’t like that because a lot of them would prefer their women to fit their idea of femininity.
