I saw variations on this theme repeated many, many times by many people. It misses the point entirely. It is not about adhering to standards imposed by the left, let alone left-imposed standards applied in bad faith to slur the right. It is about adhering to standards, period. Your own standards.
Now, Haywood argues that right good, left bad should be the only standard. This is obvious nonsense. Sure he makes token efforts to say there is room for excluding "charlatans" and the like but then he goes right back to saying, "By definition, anyone not Left is a friend." I don't know what definition he is using for friend, but I know it's stupid.
This is no way to run a railroad. At best, someone trying to follow this insanity will end up with cope like "being a know-nothing con artist is leftist" and thereby try to exclude people obviously on the right who are also know-nothing con artists. Is pedophilia inherently and exclusively leftist? It will be.
Back in reality, we do not punch right for the sake of punching right (or left for the sake of left, for that matter). We punch where there are people or ideas needing to be punched. And being on the right is not a guarantee that this is not the case.
