I agree with your observation that Charlottesville was a "state sponsored riot" clearly facilitated by the Mayor, Police, Civic leaders, and Gov. McAwful. Their agenda was nakedly clear. To foment open violence and begin the non-stop race-baiting of the GOP. We witnessed the fact that despite hundreds, literally hundreds, of public felony assaults, virtually no one was arrested.  The DNC continues "The Resistance" to mobilize violence and to stop Free Speech. We saw the DNC playbook at Trump's Chicago rally in 2016, the Inauguration, in Berkeley, in Charlottesville, etc. 

Yet the most effective methods to counter extreme messages like the KKK, etc. is to not attend their rallies. When they march in empty streets, to bellow taunts to no one, to rage against the air, and to lash out at nothing, it quickly eviscerates their "juice". Tragically, many groups I don't agree with have an absolute Free Speech right. It's why we have American Democracy. A fact the Left continues to debase.
