Here's a video of what occurred during the liberal demonstration the day after the Alt-Right rally on 5/13/17. This may give you an idea of what kind of people we can expect, althought his event will be on another level.
15:07 Wes Bellamy using bullhorn for a length of time. Other SURJ activists use bullhorns for extended lengths of time
34:00 One of the many times the crowd grabs my friends camera and assaults him in an effort to obstruct the press
48:00 I arrive. Clearly just looking for my friend to make sure he is okay.
49:00 I tear down the Black Lives Matter sign they'd draped on the Robert E Lee Statue
53:07 One of the many times my friend, who is livestreaming the event, is attacked. Rioters pull his camera away.
54:30 I use my megaphone to communicate with my friend and make sure he got his phone back. This is important because the arresting officer said I was using my megaphone "to get in peoples face". I was just using it to communicate with my friend.
56:30 I'm trying to leave the park when I'm entrapped by the Antifa. When I try to duck and and escape they squeeze in so that I have to push them off to get out
