To expand on Mr. Benson's comment? 

Everyone is marching. You are a Nazi-flag waving, Confederate-hat wearing, Ann Rand reading, basement dwelling nitwit with more tea bags than common sense? Protest all you want. It's my right to protest right alongside you with my sign 'I'm with stupid' and an arrow pointing your way. Welcome to these United States, where we still have the right to call Nazi poseur dimbulbs Nazi poseur dimbulbs. 

Protip: You can't show up to your protests armed with clubs and shields and guns and not expect the other side to ramp up to match you. Because of course we know with that stuff, you'll feel emboldened to escalate. Then you will blame it on the Violent Left. Well, be careful at those Nazi gatherings, because it's also free speech to say, "This nitwit showed up at a Nazi Klan rally. Do you know him?" and post your picture far and wide. :3
