Isn't there a way for individual users to completely hide an instance from their feed? Because I would just do that if it bothers you.
I'm not saying that some posts/instances aren't unethical, objectively incorrect, and/or dangerous, but widespread censorship is a slippery slope. If you want what you're able to see to be heavily controlled, there are probably other instances with that purpose. An instance that describes itself as general-purpose and for everyone probably isn't the place for that, though.
