I'm going to note that fascist/"alt right" violence and threat of it has been going on for far, far, far longer than people tend to acknowledge. The Giffords shooting. The armed standoffs at Bundy ranch and Malheur refuge - and shootings committed by people at were at Bundy ranch. These things have been happening since not long after Obama entered office, and ultimately, the things seen with Antifa (the real things - not the BS spewed by fascists and "alt right" to justify their actions) are a response to these behaviors. Antifa would not exist if the reason for their existence did not exist. It's in the name.
I leave you with that.
