I have to say however that a few of these ring true to me. My ex introduced me to the lifestyle, coerced me into doing things, blamed me for not sticking to my boundaries (I did, and he "forgot") and was seriously in need of therapy and still is, and used to joke about degrading me. His porn was mostly bullying/degradation scenarios to boot.

Not all kinky people are positive, and neither are all straight people. Everybody from every walk of life will have a negative story to tell from multiple contexts. The broad brushstrokes are indeed wrong from any perspective however, not just some of the feminist blogs.

I'm just saying that it's an equilibrium, and these things go in and out of flux.
