It’s one thing to burn effigies of the American president in the streets amidst mass protests; it’s quite another to act alone in lodging your frustration and anger. In the former, you’re virtually anonymous and cannot be held accountable, whereas in the latter you know you’re going to be identified and judged for your behavior.
