Most of these girls are young and grew up in a culture that tells them these things are empowering, they see all those Instagram girls etc be rich and famous from sexualizing themselves, they see men desiring them without realizing it's shallow. Some of it is due to our biology, but a lot of it is just kids that were never thought right, received no guidance, they're primarily raised by the media which pushes these stupid messages constantly. If this was truly natural and the way women want to be, they wouldn't all be mentally ill. There must be some cognitive dissonance here, but they won't question the things they do and see that they are harming themselves in these ways because it's not permissible to question the empowerment and self objectification ideas in their social circles, and would result in rejection/social isolation. Society is sick, most people are stupid, women are not especially stupid, everything about our culture is just horribly sick and you can see it in their behavior and the resulting self harm and mental illness.
