This is a tired argument, but I have yet to hear a good counter point to it when people bring up denying white nationalists free speech.

If you say that certain beliefs and movements so inevitably lead to violence that they cannot be allowed freedom of speech, for the life of me I don’t know what justification you could have for allowing free speech for Islamist’s or leftist socialists.

And if I am not making this argument from an alt-Right position, but instead from a classical liberal, capitalist, “MURICA” position, then the argument becomes even better. Both Communists and Nazi’s were socialists, and they were both anti-democratic totalitarians, let’s ban them all.
