To be clear, not talking about this community, obviously ๐.
What's the point of writing down rules, if mods just do what they want? But I suppose that's the risk you take when you call someone a liar in a small community; they might be a mod.
Edit: I'm not trying to say that mods suck, they perform a useful and often thankless job. Just that it can be difficult for small communities to get a healthy number of good mods, which can become a problem.
I mean hey, by all means if you think a community is too hive mind-y or echo chamber-y then by all means don't join. That's the beauty of small highly customized communities - it can be moderated in a way all the members agree with, and anyone who doesn't like it can find or found a different one.
I don't know what exactly you're imagining such a community would disallow, but I feel like whatever it is, I'd agree with it being disallowed. Disagreeing with someone is typically fine in most communities I've seen, it's just hate speech or any -ism or -phobes that aren't. And that's fine.
