Alright, well I'll keep this comment short then. Just personally I have it as a hobby and its helped me work through a lot of stuff, and it's something I'll cherish for letting me make people happy. Being powerless or powerful is often the fantasy, and I find that it's actually helped make happier relationships when properly explored.

A better reference point for your argument would probably be pornography. As much as I've worked there, it's insanely disgusting and exploitative in many ways, not to mention obviously objectifying. I do think there maybe should be room for exploring sexuality and it shouldn't be forced to be a taboo, but pornography in general is one of the sharpest point of capitalist decay and "horribleness" for lack of a better word. So that's better to use than BDSM.

Lastly, my general view on the topic is very similar to Dan Olsen's discussion [unfortunately a liberal] in his 50 shades of Grey series.

Edit: although...idk, I'm trying to not be angry here. It's just as someone who went through genuine abuse, having the thing that gave me a lot of comfort in my relationships afterwards be the thing being called "abuse" by anyone kinda incenses me. But I'll try to understand where people are coming from
