Seems whenever Trump supporters try to exercise their 1st Amendment Right, folks want to fight them:

Quote:Demonstrations over President Donald Trump’s loss at the polls have resulted in charges against nearly two dozen people in Washington, including a person accused of setting off a commercial firework and four people accused in an assault that left the victim unconscious on the street.

What is the purpose of the "counter demonstrators" in this matter, besides trying to stir shit up?
