liberals beating up on other liberals. Sounds like a good thing to me. A house divided wont stand.
I fear that you are mistaken what happened at this event was the launching of a new meme & that is the idea that fascist deserve to get beat downs wherever they are & anyone who disagrees with the leftists is a fascist, that is Republicans in general and Trump supporters in particular.
This little exercise was about testing tactics among the various elements that claim to be part of “Antifa” (antifascist movement (move on Black block anarchists SEIU)& to establish street cred .
This is the democrats preparing their shock troops for the GOP convention.
