“On March 3, a small team of conservative activists converged on Revolution Books in Berkeley, Calif. live-streaming their actions on Facebook with this description: ‘Infiltrating Berkeley’s Marxist Hive.’ ‘Fucking Commie scum,’ shouted one conservative activist, taunting the bookstore employees who met them at the door. He wore an American flag on his shoulders and a ‘Make America Great Again’ hat. ‘We’re gonna burn down your bookstore, you know that right?’ he said.”
