Yeah, that one’s a huge problem in our mental landscape. There’s a lot that can be written there from the damage of biological nurturing myths, creation myths, false comparisons between reproductive strategies between other species and humans, etc from a historical context (where did all the BS come from) and progression sense into modern iterations that now feed the belief system alone.
As you said, we’ve examined how those things affect how men perceive women but much less about how those things affect how women perceive women.
We have to change our perception of ourselves first and then society’s perception of us will follow. It will have to. As Eleanor Roosevelt said, “No one can make you feel inferior without your consent.” We gotta learn the when and how to say no better.
But girl power isn’t it. It falls flat because it’s trite and performative. Any kind of misplaced focus on gender performance, either one, will only add confusion to things that have little to do with actual gender in the first place. Constantly referring to ideas, character traits, abstract things, etc as either masculine or feminine is asinine and ridiculous. It’s an irritatingly bad habit for a society to get into and it needs to stop.
