For real, the main tenet of fascism is the law only applies to whom power doesn't like. Those in power will openly and flagrantly transgress the law because doing so and getting away with it validates their position in their eyes. The fear instilled by their use of violence to silence people disproportionately isnt a nuance to delegitamize, it's a feature front and center on their brand.

Fascists don't have morals. You can't treat fascists like they were a normal group that respects social dynamics, because decorum only applies if both parties respect it. If one side decides to not play by the normal rules, then decorum will be used to hang you, because you are bound by it and predictable, easy to outmaneuver. The way to handle a fascist is the same as when you need to put the family dog down. It's your duty. It's not a joy, you take no pleasure in it, you make no speeches, you don't waste time, just dispatch them. no monologues. End it. Fascism has to made afraid to show it's face, or it's going to eat all our faces.
