The logic of fascism is this: “Your X constitute[s] an act of violence, so I’m justified in using violence against you.” For X, you can fill in just about anything except actual violence. Some of the more popular choices are: “Words; Opinions; Positions; Race; Presence; Borders; Jewishness.” Once you equate any of these things — anything — with violence, once you feel justified in committing violence in response, your actual positions no longer matter. You’re a thug. You’re a fascist. You’re a tyrant, petty or otherwise. You no longer have a place at the discussion table.
Violence is not in the same category as any other human interchange. Our right to life and safety is our first right and the one on which all others depend. Free speech, religious freedom, freedom of the press — none of these means anything if people are allowed to hurt or kill you for them. That’s why every civilized system of law recognizes: Violence is justified only as a response to actual or threatened violence. You can say the most awful things to me, but if I can’t show that real physical violence was a reasonable threat, I can’t legally respond with force.
Even the logic of fascism understands this — and seeks to disguise it by labeling as violence what is not violence at all: your words, your opinions, your race, the fact that you’re a Jew.
