I’ll go with the low-hanging fruit: Mein Kampf. I’ve read it, cover to cover. As a piece of propaganda, it’s good. As an example of good writing? Absolutely not (though I will admit I have only read it in translation). Oh, and the whole fascist, racist, and generally shitty worldview of the author that he infuses into the text. And the fact that the author is literally Hitler. You 5-star that book? You’re a Nazi. Period. And as a Jewish person, I don’t look too kindly on them.
I should read this one. I almost always disliked the people who cited it as the most important book they ever read - so I can criticize it, but actually know little about it. Just seemed interesting that the people who talked about how wonderfully meaningful it was, also seemed to be selfish and practice constant virtue signaling with no actions to back it up. Is that in the book?
