The marketplace of ideas evaluated the ideals of Nazism, and rejected them by itself the first time. The fact we even call them Nazis is testament to that - it's an insulting reference to the fact National Socialists were uneducated country bumpkins. In battles of wits and words, Nazis lost every single time. So the idea we need to violate our ideals about freedom of speech, to defeat an enemy who never did stand a chance against us in that way, makes no sense. Do you really think our society's beliefs are truly so weak? That we are truly that vulnerable to pernicious memes?

Now, if you want to talk "never again" - it is not words that should frighten us, but violence. It was the brown shirts working the streets and savaging anyone who dared speak contrary to the Nazis that allowed them to obtain real power in the elections. It was the night of the long knives that saw the Nazi's staunchest critics in the Reichstag assassinated, and Hitler's control finally secured. It was the night of broken glass that normalized widespread violence against Jews, and set the stage for what was to come. It was violence that gave strength to Nazism, that let it rise to prominence, that let it overcome the Prussian elite who despised it and let it seize control of the country.

Nazism only succeeds by first putting its boot to the throat of the public, and threatening to crush the windpipe of any critic. Without that, it is just incoherent, anti-intellectual gibberish concocted by brutish thugs - and is torn apart in the market of ideas as a result. I fear a non-violent Nazi about as much as I fear a toothless wolf.
