I don't care for this opinion because it ignores the fact that men and women can both lack the grit or whatever it takes to go against social norms. The reason you gave is not a "woman-only" reason, it's definitely a possibility that the majority of misogynists (from both genders) don't feel like it affects them either way but are just afraid to think too much about it. Meaning they'd rather accept the status quo than argue for change.
Honestly, I'm normally outright hostile when somebody who is disabled, neurodiverse, or a member of a minority/persecuted group says they don't feel that they have the intellectual or emotional capability to have equality so I'm actually really offended when you act like most women just can't rebel against what they're taught to believe.
It's not that easy. Not only are we brought up to believe a certain thing, but at every turn it is repeatedly hammered against us. It's easy to not have general biases -- like believing men and women are equally capable of being great leaders, deserve the same rights, jobs, etc. It's the more subtle things that are much harder to escape, and even if you know better you have to constantly correct yourself.
Simple stuff like automatically associating women in power as bossy or bitchy while not thinking the same or equivalent of a man in that position, thinking women inherently do better as teachers, secretaries, nurses, caregivers, etc, valuing and judging women based on their sex appeal (she looks too slutty, she looks too prudish, she doesn't wear enough makeup, she wears too much, she doesn't smile enough, why doesn't she wear heels, why does she wear heels, etc etc), the list goes on. These, amongst others, are things that I, even as a woman who knows better, constantly hit my head up against because they've been so systematically ingrained into me. There are an endless number of little things we're taught to believe, and rebelling against them isn't always easy, especially when living in a society that can actively punish women trying to go against the grain. There's already been users here describing how they purposely act certain ways (heck, I'm p sure I automatically do it myself without even realizing) to avoid potential trouble - sometimes even dangerous trouble - with men.
Quite literally, you can be a women fundamentally against misogyny and still have thoughts and ideas that you don't even realize are misogynistic in nature because they can be so expertly woven into normalized mentalities. Certainly there are going to be many women who just go along with the norm and even willing participate because it's easier, but just as many women struggle with even trying to help it within themselves to begin with, and more are basically brainwashed from birth to believe these things unquestionably. Every single woman is still inherently a victim of these biases and a victim of internalized misogyny, regardless of whether they knowingly participate in them or not,
because they are playing part in a system that fundamentally values and respects men over women and systematically teaches and reinforces those values.
Edit: Also I want to add that, yeah, it is absolutely freaking frustrating as hell seeing another women agree with and play into misogynistic mentalities. I get real angry when I see it cuz it just makes everything all the worse, so I can understand the angle you're trying to come from. But that doesn't negate that they're still victims of internalized misogyny and what Delphine is saying.
