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.
