Professional troll gets a reaction? She even demonstrably repeatedly lied about her level of involvement in her own video (and we likely don't get to see everything she did) then complains when she gets chased off and her hat shoved in a bin. She said that people punched her but I didn't see any evidence of it, and frankly I don't see any reason to believe her when she obviously lied at least once in order to paint the picture she wanted to paint in that video.
I bet that at virtually any demonstration anywhere in the world one can troll people into reacting angrily. In any civilised country, it's pretty reasonable to assume that anyone at a demonstration is pretty angry about something, so they're easy to troll.
I'm not sure what point you think she has. If she asked a reasonable question to those people and conducted herself in a respectful way and got an unreasonable reaction, that would be a different story. Instead, her opening play was to label everyone present as fascists and telling someone that she thought that they were all a joke. That was just the bits of the video we get to see. Meanwhile she's blathering about freedom of speech as if it's a shield that should stop people from reacting angrily to what she said.
