Do you believe that killing political rivals makes a movement a revolution? Is Assad in Syria running a revolution? The Nazis went wild with murdering everyone they didn't like after they got elected (not that they weren't into violence before, but Hitler's attempt at a revolution failed in '23, Hitler was convicted and went to prison). They got elected on a populist vote, but that's not a revolution. Revolution != getting elected by normal proceedings.
