I honestly think it’s about degrading the right to free expression. But yes also probably. The people who cast women and kids as pawns in need of protection are usually not super respectful to the real women/kids in their lives.

Pretty sure the normalization of sexual violence and harmful attitudes came from the adults in my life. If parents and teachers adequately teach kids to identify those things and know that they are unequivocally wrong, then teens who see unhealthy stuff in porn will notice and be critical of it. Probably indignant, too, since no one is more justice focused than a teen who has just learned something about the world.

The issue is backward ideas about relationships being reinforced by adults, either through active misogyny or just never talking about it. This argument boils my blood because the porn itself is not the problem. Awful attitudes about relationships and women start very early and they often come directly from parents themselves.

This isn’t that far off from how existing u.s. policy about health and disabilities works in practice, though. There are some patchy safety nets (deliberately underfunded and full of glaring huge holes) but basically if you are not healthy enough to work and you’re not also very very very lucky in some other ways, “just die” is basically the indirect message you get. Disabled people do not actually have equal rights.

So there is a fascinating historical rabbit hole here that I went down a few years ago. I think it is Nicole Rudolph who did a deep dive video into the history of bras and other shapewear. If you smoked a lot and like history I recommend it.
Bras and similar garments give the proper ‘shape’ for the clothes and cultural norms of the moment, and give people comfort and support if they need it. Lots of people need something sturdy to keep everything in place, but it’s also still a very grey area of social acceptance to choose not wear one.
