Trump cheats protestors from planned activist set up to create bad press at his rally! Well done, Mr. Trump!
Exactly! It’s a venerable old anarchist’s gambit. Escalate violence at a “peaceful” demonstration, until you get a reaction from the authorities (or, in this case, the target); then scream “Fascism!”. The objective being to get the masses (lumpen proletariat, low-info voters, etc.) to condemn the target of the violent demonstration for violence. How many more centuries, before the masses catch on?
