BEWARE the Reverse-Mussolini Fallacy. “People fall prey to the Reverse Mussolini Fallacy any time they make an argument to the effect that ‘bad people believe X, therefore X must be wrong.’ The flaw in this reasoning is that bad people can still be right about some things. In the abstract, almost everyone recognizes that. But many still fall prey to the Reverse Mussolini Fallacy in practice, even if they understand its flaws in theory.”
