When we had a bunch of white supremacists driving in their lifted trucks, yelling at the BLM protestors and threatening violence against them, there was no use in trying to argue with them. They were just interested in getting into a fight so they could justify using their guns in "self defense".

This is a false dichotomy. There are effective ways to defeat Nazis beyond punching them or reasoned debate.

Violence is justified in life or death struggles where other options have become unrealistic. That’s not the situation we’re in in the West 99% of the time. Deplatforming, doxxing, civil resistance, and various other forms of nonviolent struggle all have a better track record than street brawls which have done nothing but empower fascists. In fact, the sense of fear and chaos that these events creates is exactly the environment in which fascism will thrive. Street brawls between fascists and leftists were prominent in the Weimar Republic and did nothing to stop Nazi power—if anything it made it easier for the right to unite and paint leftists as unreasonable extremists. We see similar patterns happening today.

Politics is not the same as armed struggle. We are not engaged in armed struggle against fascism in the west. Perhaps we will be but right now one of our goals should be to avoid that becoming necessary. In the current moment public relations and persuasion matter immensely. Punching Nazis achieves little other than making people lose sight of the dangers of fascism and focus instead on “extremism” from “both sides”.

And OP has done nothing to suggest they are sympathetic to fascism so your threats against them are extremely rude and unjustified.

Edit: I also should have stressed that the most important thing is to organize. People power is the real power. Collaborate with and help everyone, not just your Maoist book club or whatever. One of the ways the Fascists won in the past is by dividing people and going after minorities one at a time. If things do devolve into armed struggle, you’ll be much better prepared if you’ve got deep roots in the community.
