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.
It’s a pretty important historical text that gets engaged with more by people who are seeking it out for historical context and understanding than most texts of the sort that are mainly sought out by those who agree. Not so much people brigading, just people who don’t share the views of the author being more likely to have read it and be disgusted by it than most hate texts because of the historical significance to a time period that many have interest in and that we’re still seeing consequences of to this day
