Let's first appreciate the parent of your comment being down-voted for saying leftists don't take critique, confirming the point. In my experience, the insufferable ones tend to dominate communities, making the entire place unappetizing. You can see this effect on Mastodon too. A tiny group makes all the posts, and they have 100% ideological consistency. I think that's an effect much more important than arbitrary rules of an instance, because this happens before it. People aren't banned, they are discouraged from posting at all and become the silent majority.
