See Patreon for example. Or see the sex games that get banned from Steam, vs the ones that stay. NSFW is sorta allowed, but there's no real consistent rubric. Once you start actually organizing or tagging kinks, pretty much everything outside of vanilla pisses someone off. It seems like not really advertising kinks is the way to go for now.

And that 'someone' is usually the payment processor (paypal, mastercard, etc. etc.). So I recognize it's not Patreon fault per se (which is probably why it's so inconsistent).

Some of the most sex-negative people in my social circle are atheists btw. Sex negativity is shared on both the left and right.

And strangely enough, some religious people I know are strangely sex positive. (See the myriad of gentlemen's clubs in the south). It's not so cut and dry as just blaming religious groups on this one. Yeah, Church and sexuality don't really match up but its not like everyone believes 100% what the various churches preach.

The citation is all the media produced by Hollywood and Netflix that gets exported to the rest of the world. It's a lot more obvious to see if you have a different culture that doesn't glorify violence as much or is more open about sexuality.
