they have a very fragile echo chamber

They have an active moderator base.

I've been banned from plenty of communities already - particularly meme communities - in the wider Fediverse for rubbing a mod the wrong way. It isn't particular to .ml and it's silly to see Lemmyites panic every time they see an .ml instance user or post.

unironically calling north Korea democratic

So what? Plenty of people in America call Florida democratic. You'll be screamed at for suggesting otherwise (Florida voters are just too stupid to vote correctly, you see).

If you get in a pissing contest with a mod or power user, there are plenty of communities that will ban you for being toxic. Either learn to exit the conversation gracefully or stop sticking your dick in the social media blender to begin with. You're probably better off getting banned than running back in for another screaming match.
