I read Andy Ngo's book, which is about his endless research on Antifa scum, how the media and courts protect them and lie about them, and how they inflict violence on any who question them (including Ngo himself, who suffered brain damage from one of their many physical assaults on him).
His mountains of evidence that Antifa is a savage, violent criminal organization (and yes, it is heavily organized, no matter what NPCs on Facebook tell you) are useful, and he even has a chapter about Antifa's 1920s communist origins. I've witnessed (former) friends repeat blatant media lies like "Antifa is an idea, not an organization" and then go on to say that Mitt Romney is a fascist. It's maddening how stupid and easily tricked normies are, so it's good to get the truth out there in book form.
Ngo's book is harrowing. The cruelty and terror from these anarchist/communist shitbags goes on and on, and everyone with power allows it. If Antifa attack you, YOU get arrested and lied about. The book is as bleak as any dystopian novel, except it reflects reality in Piss Earth 2021. Highly recommended.
