I've dipped in and out of the kink scene. I'm a lesbian so my experience will differ slightly.
At university, 95% of people there were die hard liberals, most were queer, and everyone was very keen on consent. Anyone even remotely coercive/abusive was booted out. There were plenty of male subs/female doms. All the women there would have considered themselves feminists. Kink done properly encourages very open communication and very very clear boundaries, which let's be honest, is something a lot of vanilla couples never discuss. I can honestly say kink has made me very sure of my sexual preferences. I know exactly what consent looks like. I'm very forward with my preferences, and have no shame in communicating them. A lot of my vanilla hetero friends struggle to communicate to their boyfriends if sex is poor/they're doing something they don't like. There are also plenty of taboo kinks in the kink community.
Tbh, a lot of the submissive women I met were very confident outside of a kink setting. Some people use kink as a way to process trauma, but honestly, it's mostly just preferences 🤷 For some people there will be a patriarchal element to it, and the desire to be dominated by masculinity, but it's not always that deep, lol. I'm personally very submissive. I like being hit/spanked/caned/humiliated etc. I don't like it due to any particular reason/due to trauma. It's just what I like. It makes me feel good, lol. I'm highly anxious irl and it's just a good way to let go of control and relax. Also, domme women are just hot AF, and I love the way it subverts gender stereotypes. Nothing as sexy as a woman telling me what to do.
In the non uni world, there are a lot more creepy men around tbh. Most men do Dom and not sub I would say. There is almost certainly a patriarchal element to this and lots of power play involved. You have to be very careful who you play with. But it's still similar in that anyone doing something they shouldn't is quickly dealt with if you have decent people running events. As with anywhere else, there will be some women who are very vulnerable attending, but the vast majority just like what they like. Because the kink community is so open, imo it's easier to see when your being abused.
