Generally FF, but I'm absolutely no fan of the violent ultra-left. In Europe, it's called the Black Block, in the US it's just crazy ultra-leftist students.
I wonder if there is a concerted effort by people online or investigative journalists to 'out' antifa and other violent left protesters who are identified by video or eyewitness testimony. Such as going to their place of business and downrating the business, sending in petitions, etc. I don't have the time to do it though it seems some of my FB friends are in that crowd to do it to people they consider as racists, neo-Nazis, KKK, and white nationalists.
