* Why do little girls suddenly start to ask if "boys are better" when they get to school?
* Why do we feel the need to tell people out opinions about how they look?
* Why is a tattoo of a butterfly on a wrist okay for a woman but not full sleeves? (Contrast that with men.)
* Why do we insist on loudly proclaiming our daughters are "not like other girls" or are "like a boy"? Is there something shameful about it?
We took away agency long ago and we've been dangling it in front of oppressed people for years, periodically letting take small bites. That's another form if how me keep a grip on things. We give people a taste, as long as they're willing to take the conditions that comes with it.
There's a thing called "choosey choice feminism" that is a hot button item. One side days "following the magazine standards is a choice and I'm free to make it because feminism" and the other side says "but why do the magazines exist and would you choose that if you weren't bombarded by it all day?" I think both sides are right but I also hear and see the problems. It's not about whether or not feelings or opinions are right though, it's about what you'd feel or think if you weren't subjected to it constantly. To ignore the external influences and dismiss patriarchy is to accept the status quo as a Good Thing and be okay with slut shaming and demonizing the very freedom of choice you're trying to defend.
I don't see how this works well for long (and it arguably hasn't) because of th cognitive dissonance required to accept all things to be true.
It's not about whether their opinions are right, it's about where they're valid. Women can have opinions that aren't correct, just like men are free to be wrong. When you say it's about what they would feel if they weren't subjected to it constantly is totally subjective. Some might say women would run around naked because it's more comfortable without societies pressure, some say they would cover up because taking off clothing is a societal pressure to appease the male gaze. But then again, the assumption that all women would think that same is just more simplifying them and their views.
In reality it'd probably be a mix, because women can dislike other women without it being because society brainwashed them to. Saying they wouldn't ever be rude to one another if not for society feels like that patriarchal idea that women are all innocent flowers that must be protected from bad influences, rather than they're normal people who are nice and mean and everything in between. If you're gonna go into the territory of "what if everything were different" you can't also declare you know exactly what would happen. And yes society has taken a lot of agency away from women, but the solution isn't to take agency away from them in service of feminism. This just leads to a different set of problems for women
little boys also ask if girls are better when they get to school. both sexes are curious as they grow up. school is also dominated by female teachers and there are now more girls in school than boys.
the rest of your questions are nonsensical. people are people. norms exist. they might change but there will always be norms, and they will be tied to masculine and feminine expressions too.
