I'm not a Nazi, I don't give a fuck about the Jews one way or another, but my politics do lean towards the authoritarian right end of the spectrum. I'll try to explain this to you as best as possible.
This line of reasoning can be applied to pretty much any ideology that isn't laissez faire liberalism. By this logic, you can't be Christian and be into femdom (sodomy), you can't be Muslim and be into femdom (sodomy again), you can't be communist and be into femdom (bourgeoise degeneracy), etc.
Hell, I could even make a progressive argument for why femdom porn is bad. Afterall, femdom is hot because it subverts and reverses gender dynamics. If there's nothing to reverse, the taboo fades, and the fetish becomes superfluous. Thus, it could be argued that femdom is anti-feminist and reinforces gendered hierarchies by limiting their subversion to fetish fuel targeted at men.
This, once again, could be argued either way. I could just as easily argue that men who like femdom are more prone to be totalitarian because you have to value masculinity in the first place in order to value its deconstruction. In other words, liberal men don't get turned on by femdom because they don't believe masculine men exist to begin with. Furthermore, its a common phenomenon that people who are submissive sexually tend to be dominant interpersonally. I don't even think you're completely wrong, but I do think it's a lot more complicated than what you're implying and has negative implications for both sides of the political aisle.
And I resent the idea that being into femdom makes any of us "both straight and queer". Straight people make up over 90% of the population, we have room for a little diversity.
What's funny here is that you're basically making an argument for a stronger conservative government yourself. Its extremely obvious that the current OnlyFans culture has gone too far and is in need of correction- correction that can only come from a right wing government. The left has no incentive to legislate away porn and "disempower women" and libertarians are a meme.
