I've had a fair few arguments with some of my rad fem friends around this.
I'm not into BDSM myself, but some of my good friends are / were when they were younger.
I feel what my rad fem friends - and some on this thread - are missing, is that BDSM doesn't always involve a man who gets off on making a woman submit.
Sometimes (and always for my female friends who are into it, no idea how typical it is), it's the woman driving the dynamic. The man isn't necessarily being dominant because he gets off in it, but because she does and has requested it.
I have absolutely no doubt there are a zillion arsehole men who are using the BDSM world to get their kicks abusing women. But to think this is always the dynamic is short sighted IMO.
One of my exes, for example, had a previous ex who was into BDSM, and I know he did all kinds of stuff I wasn't into with her previously. My overall experience of him, though, was he was eager to please, not that he was into BDSM, nor that he wanted a dominant role. We were together for ages and very open with each other, it wasn't something he was missing in a relationship, it was something he did to please her, when asked. His turn on was making his partner turned on, not dominance.
I tried to explain this to a couple of my rad fem friends who have strong opinions on BDSM but they refused to understand there could be a dynamic where the woman was in control, or where the man wasn't getting off on abusing the woman. It seemed that was central to their understanding of BDSM and they couldn't see anything outside of it.
