The book is ok. It's a little mini history of anti-facism and may help demystify it for some folks who may not know that regular people have been fighting fascism for a very long time wherever that violence and oppression occurs. There's a chapter on free speech, what that is exactly, and its limits. As it was written in 2017, there's a lot of discussion of trumpism as part of the fascism they/we are anti. But as for being scary or inciting violence - or whatever we are blaming on the left currently - you won't find that here. 

I wanted to read it because there was a lot of fearmongering and artificial concern and overblown claims about antifa being evil in 2016. Reminiscent of the various waves of anti-communist silliness that pops up now and then in the US (and more dangerous HUAC, blacklisting, and assassinations of Black Panthers in the 60s). I always like to read these things people are scared of to see what exactly it is, can i easily draw that conclusion too. I failed to find anything scary. But maybe if you put yourself in the shoes of Nazis or white supremacists it'd be scary? I don't want to do that.
