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.
No, I could not disagree more. There isn’t just one way to enjoy a book. You can enjoy the ideas or the voice of the narrator, or the narrative itself. Lots of ways. Same with music.
But yes, please go on limiting your life experiences by eliminating people from your life that don’t see art the same way you do.
