Yes, the alt-right racists Trump caters to as well as Bannon, a proud racist, are fully responsible. 

Sorry, you don't believe that black lives matter as much as your life, which is the purpose of the movement against wanton violence against blacks. Got news for you, the BLM movement is NOT a movement of thugs albeit extremist thugs have taken advantage of peaceful protests to stir things up, which is the focus of alt-right racists' claims.

"Knock off the drama" of the death of an innocent person, and 19 injured. How very compassionate of you, but no surprise from the alt-right.
