I wasn't arguing that sexual promiscuity in itself breeds violence towards women. In fact, I'm all in favor of being open, realistic and not uptight about sexuality. Oftentimes, it's the people who are raised in households and go to schools that refuse to tell kids the truth who grow up to be the most "deviant" in terms of sexual habits. I firmly believe that to stifle the sexual desires of a person and label them as bad, wrong or evil is one of the most mentally damaging things that a parent can do. It often wounds the very core of a person for the entirety of their life, unless they get therapy for it.
It's more the idea that "anything goes" in terms of sexual practices. I mean, if a person has a kink or a fetish, they should indulge it in, safely and with people who share it or at least are willing to tolerate it in their parter. But to a significant number of younger people, "normal" sex in porn isn't enough anymore, they view it as bordering on boring. There's this constant push towards the outer fringes of sexual habits, towards the ever-more-extreme, and I think that's why we're seeing such a massive growth in gagging/choking/torture/rape porn.
So, generally speaking, there needs to be some kind of moderation. To try to shun or condemn sexuality isn't just futile, it's not ethical. But to go on the completely opposite end and say that, sexually, anyone can do anything they want without consequence--and that a significant number of women would enjoy being forced to gag until they puke--isn't, either.
