A meta-observation: the logic underpinning bothsiderism or whataboutism, correct or incorrect, is that everyone is equally evil and there is no sincere goodness, so any attempt to punish a particular evil is itself evil and insincere. By its own logic it can't say that the action it criticizes is wrong -- its own criticism can't be sincere -- but it justifies opposing or at least not supporting the action. The world is just funhouse mirrors. Moral judgment is impossible.
