Here is a well reasoned video discussing the incident at Charlottesville by a reporter who was in the middle of the protests and an atheist philosopher. (The reporter stated she sprinkled herself with holy water for protection, so may be Catholic!).
The gist of the video is the dichotomy between the acceptance of identity politics of the left and the renunciation of identity politics of the right. It relates specific activities by the government and police towards the right vs the left. In this situation the right being shut down through denial of permits then police action, while the leftist antifa protestors having no permit, and yet once again the police disappeared during their actions.
At minute 16:00 the philosopher states when a political system shuts down free expression of ideas and grievances it always leads to violence using the idiom “free speech or blood in the streets”.
Well worth a few minutes of time in this period eroding political discourse and civility.
