Women can be misogynists too. We don't have a monopoly on that. We as a collective value conformity because it keeps people in line and doesn't threaten our existing architecture. Things that deviate from norms draw attention and inspire discussions like this. Too many people thinking about coloring outside the lines and then more will do it.
If we didn't indoctrinate our kids at the start, we'd have a higher chance for more uniform distribution of power. More people would be able to achieve success, which would raise the floor and make the ceiling not feel so high. Those on top would feel like they're losing because the gap would shrink and the perceived height from the top would be lower. Can't have that so we say things like "boys will boys" to dismiss shit behavior, glorify #boymom, defend our girls by saying they're "not like other girls" and sell little girls on shiny object and lacy dresses, even if they really just want to play with dinosaurs (because dinosaurs are cool and not only for boys).
Patriarchy, ftw! Red Pill, yay!
