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 IS a tricky one I think, because at least from what I’ve seen the fan base has kind of reclaimed the series? Idk I know a lot of non cishet people that grew up loving and still love HP even though they hate Rowling.
That being said I’m not in any way trying to diminish your answer, as Rowling really is a shit head
She said anyone who supports the series supports her, and she is still raking in cash and using it to make our lives harder.
