A Nazi in a bar makes it a Nazi bar. A Nazi bar in a town makes it a Nazi town. A Nazi town in a state makes it a Nazi state. A Nazi state in a country makes it a Nazi country. A Nazi country in the world makes it a Nazi world.
You can construct gradients of connection for anything, but that doesn't make them not insane. If .world is a Nazi website, then .ml federates with them, so they're also Nazis. And hexbear federates with .ml, so they're also Nazis. And this all stems not from .world actually tolerating Nazis, but just being kind of center-left normies. When you're eager to make everyone a Nazi, the accusation loses all meaning.
