I'd say that, as a rule of thumb, if someone isn't bothering other people (to be clear, "I am offended" does not count, lol), then I'd say that people should enjoy and entertain each other however they please. Does it really matter how? Why is it anyone else's business?

In principle, I shouldn't even really have to get into considerations about War on Drugs type harms (an "intervention" can be harmful in itself in a lot of ways), or other harms from censorship (or someone being plain mean about some kink...)
