Which, at least in modern history, has always been fueled by bigotry? I'm not sure that was a super opinionated take considering the subject, and I'm not sure I can think of another motivating factor unless you are scared of knowledge in general. The Church attacking Galileo was bigotry. It is kind of a thing.
Do you feel there are other good-faith reasons that justify these efforts?
Are you just frustrated at hearing that word?
Perhaps. But there is a law in Florida making it a felony for the teacher to have that book in the classroom.
There's a difference between espousing a principle of "the more you read, the better your education", and "Mein Kampf is my favorite book".
Given how badly it is actually written, and the central theme is "Adolf Hitler: How I Became An Antisemite", I'd wager that the union of people who see it as a favorite book AND are not neonazi antisemites is almost infinitesimally small.
That's not to mention that, emboldened by their success in school libraries in some areas, these same people are now going after public libraries, too.
