Not all kinks have to be accepted. We should accept that it's normal to have these kinks and not shame the people for it, but some practices of kinks shouldn’t be supported or normalized as a good thing. Talking about cnc mostly. It is dangerous to participate in it and people should be wary to even consider it if they have these fantasies. It's okay to have all types of fantasies, but not every fantasy is good for the person or anyone involved. Critical thinking is important in this context. But I agree with the rest.
Boundary setting, LGBTQIA acceptance, and kink positivity, and enthusiastic consent are requirements of a sex positive culture.
