Not only that, but make the protest a positive, inclusive one where reasonable, rational people can express themselves without confrontation, destruction, or violence. Do like the hippies did and bust out some bongos, acoustic guitars, smoke a few joints, and sing some harmless, insipid songs about peace and loving your fellow man/woman/trans/wombat/or however you/they/we choose to identify.
What does anyone think is going to happen when you try to confront or assault a bunch of Klansmen, neo-Nazis, or the like?
