Yes.

Which is the rule of lemmy.world that protects NATO as a bastion of Western European freedom?

There isn’t one and there’s plenty of anti-NATO / anti-western / anti-capitalist sentiment here on lemmy.world.

Are political discussions beyond centrism banned on lemmy.world?

Obviously not, we’re still federated with lemmygrad and lemmy.ml.

Feel free to do what you feel is best for yourself but I think this situation with hexbear is being blown way out of proportion, mostly by people who seem to have a vested interest in that instance being able to participate here but not the other way around.

I’m some sort of Classical / Moderate Liberal and occasionally “talk against” NATO but there’s a wide difference between that and actively pushing to see it disbanded which is tantamount to Pro-Russian propaganda…especially right now.

If you can’t handle a rule preventing you from trying to remove a bastion of Western European freedom then I guess you’ll move to a new instance.
