What are you on about?
If there are protestors blocking the streets, that doesn't give me the right to drive through them. The protesters were blocking one road and leaving another one open An annoying detour and a counter productive protest? Perhaps but them being annoying doesn't justify threatening to run them over. The other angle of the incident shows that he was already driving with one of the protestors in front of his car when the mob surrounded him, otherwise why do you think they did so? The worst any other car got was a relatively light smack as it was driving away along with some taunting.
I get you guys have a hate boner of Antifa, that's fine because they're pretty annoying and do cross the line. But this whole incident was mostly a nothingburger with the worst part being the driver threatening one of the protestors with his car.
