I hate to say this, BUT...
Everywhere BLM protests, highways get blocked, windows get smashed, and looting occurs.
Everywhere Antifa protests, people get beat up and sh!t gets set on fire.
If BLM and Antifa didn't show up to "counter protest," I bet these douchebags in Charlottesville would have just marched along, shouting their stupidity, and no one would have gotten hurt and nothing would have gotten broken.
That, of course, does not excuse anyone from ramming a car into people by any stretch of the imagination, but BLM and Antifa were there to provoke, and they know it.
