Are there people pretending to be kinksters just to physically and sexually abuse women? Yes, of course there are. Does that mean that's what kink is all about? No, of course not. By this logic, all types of relationships are inherently abusive because some people use them to abuse. Don't speak for it if you don't understand it. In fact, you regressive assholes should try shutting the fuck up sometime.
Oh, and look at that. Now people who don't do sex the way you like are degenerates. Slippery slopes. Immoral. Moral decay and people "subjecting" you to some horror just by existing in a public space. People deserving to be punished over sex, societies deserving to be wiped off the earth over sex. Are you trying to sound like oppressive religious cishet-sex-for-procreation-only types to try and gain their approval or have you swallowed their propaganda so much that it's the only thing coming back out now? Folsom is a very well known and well advertised street fair that has visitors in the hundreds of thousands, it would have been very, very easy to avoid if you didn't want to see it. And even if you somehow just accidentally stumbled upon it and saw something you didn't like then once again, it's a street fair. An open space. Just turn around and fucking leave. No one would stop you. If you don't consent to seeing dicks, then you should just move away from the dicks-out area, dumbass.
You're just turning into another alt-right indoctrination chamber but with pink wallpaper, and you're too hopped up on the immense, senseless hatred you have for one group to even recognize that you're getting manipulated into hating more and more. At this point I wouldn't raise an eyebrow if ovarit posters started ranting about how (((the elites))) are ruining Western society or some shit.
