People are so worried about "echo chambers" when it's sensible people/marginalized people trying to find safe/sane spaces. But like, where has keeping "diverse" spaces gotten us? In the sense of, where is the reward for allowing conservatives and bigots into common spaces? It hasn't made them more reasonable. It's just made us less safe, again and again, and normalized fascism and hate as valid and acceptable viewpoints instead of toxic ones that should be pushed out.
