I think the comic is the one that is pushing sillyness about lesson planning, it’s saying not to do to that and instead just assume the banned books have value simply because they’re banned.
Why don’t we just agree that there are plenty of books on the list that genuinely don’t belong in schools and that if we have a problem with the legislatory system we should propose sensible ways of screening books rather than pretending every banned book is Ray Bradbury and acting like every time a book isn’t passed for inclusion in the curriculum it’s literally nazi 1984.
