Good points. I think it is far easier to make the argument that porn has been bad for women because they have less the power to control men via their lust.
And maybe that is why so many women now seek power and control ('manipulative') and seem so unfeminine, rather than being what we think of as the traditional wife, because they lost the power and control (via a man's lust) that they naturally had since forever, but they are still seeking it because evolution drives them to.
Maybe that's a "win" for men, that we can't be so easily manipulated. But I think it's a further step towards an unnatural and unfulfilling life.
