If it's roleplay, and the participants are able to acknowledge this and function in society while adhering to standard social norms, that's one thing. But to my knowledge, many of the Gorean types are the ones that don't see it as roleplay and see it as a genuine lifestyle. These are people for whom the idea of regressive male/female relations are a fact of life.
If it's roleplay, that's a completely different discussion and it isn't something people should really get worked up over. But one of the big differentiators that I've heard between Goreans and the typical BDSM scene is that the Goreans live it and don't play it.
And you know what, if it means being called an SJW to say that kind of lifestyle and view of other people is fucking horseshit, I'll take that label gladly.
