It's worth a read.
Like it's full of absolute horseshit and batshit takes on history. I spent the first couple chapters checking their citations / references. They were mostly misleading citations, and snippets of things, mashed very poorly into a shape that they then tried to wedge into their fascist manifesto. These shit heads literally quote twitter to try and prove points. At one point the author cites his own op ed. But like, even the stuff they're trying to cite to support their arguments, if you want to pretend that twitter was viable as a 'source', they're pointing at posts by ppl with 100k followers, which have just like 300 upvotes. So even in a captive audience that's at least in theory 'interested' in the drivel these guys spout, only 0.3% of the people agree. They even include things like twitter post grammatical errors that botch the message.
A more concrete example: they claim at one point that Scott Adams (dilbert) was cancelled for saying (paraphrasing this): "Just one thing, that everyone agrees with: that you should avoid groups of people who hate you". I mean, a quick search finds a bit of controversy related to Adams saying something more direct/overtly racist, like "White people should just stay away from black people". He also had a history of similar such comments going back years and years before he lost a bunch of his distributors. But these neo fascists are just like "nononono, just look at this one thing, that we've totally reframed to try and make it less racist! Now pretend that single de-racist-ified comment was the only reason he lost work / people stopped wanting to see his stuff! See! Evil unhuman lefties!".
It's really something else to see this sort of drivel, lauded by these core right-wing figures, be so shittily constructed. Like the most basic checking of their assertions, makes it fall apart. Every page would be filled with corrections, edits, issues, etc if this had gone through any higher level peer review. In that alone, its worthwhile to read it to get a sense of just how rigorously the "elite" of the USA actually think about .... anything.
