Mr. Congressman will you please go fuck yourself in the most violent way possible?
The nazis planned their own march. They encouraged people to come to the protest armed. Preferably with firearms. They announced to the public they were going to be armed. They were planning for, expecting and trying to agitate a violent encounter at the rally. Preferably a shoot out. They came looking like a lynch mob, not like a civil rights march.
Whatever violence ensured from their march was entirely on their heads.
You don’t get to claim you were marching peacefully when you bring guns to a rally. You want moral high ground, come unarmed and show some backbone.
