I think the thread has drifted sideways really.
I don't think BDSM should be accepted, normalised, minimised, sanitised, whatever.
Normal people, or even people who are into it, are entitled to find the things that other people do to get off disgusting, weird, twisted, perverted, unhealthy, etc.
If people do get off on deviant stuff that is reviled by the mainstream they've no reason to be poor diddums about it. They are choosing to indulge that part of themselves and prioritise getting off over being respectable, or whatever else they stand to lose.
The fact that they are getting off on what a lot of people would see as abuse (domination, humiliation, pain, restriction, etc) is going to be eyed with suspicion.
Currently the worst kinds of cruely and abuse are bring carried out in the name of BDSM and that is a concern.
Abusers and narratives that enable abuse are the problem. None of the problems stem from feminists having visceral reactions of disgust, concerns, judgements, etc about sexual deviance. However it is a lot easier to tell off and blame women for being unsympathetic and frosty than to confront abusers or members of the judiciary that enable them.
