Another community having the possibility of posting something you don’t approve of when nothing is actually illegal, nobody is actually getting hurt, and you could just have blocked that community (or even just offending users) for yourself in the first place is just a really dumb reason to force the whole instance to defederate from it.
It’s up to Ernest what happens, but I’m not on board for unnecessary censorship of cartoons, of all things. I honestly worry for you.
