Said women have every right to do whatever, including doing SW. This is not an individual problem.
The problematic part is people actively searching out and forming communities around pron with women looking as close to a kid as possible. Condemning those guys has absolutely nothing to do with the people in the content and in no way shames them.
It ain't the women at fault, nor the content inherently, it's the context and people fetishizing them in a way they prolly would't be comfortable with in the first place.
