I remember being in school decades ago and our very left-wing English teacher telling us about the Catholic Church's index of banned books, which included things like Henry Miller's Tropic of Cancer. At the same time, you also had a big push by Evangelical groups in the U.S. to ban books like Deliverance from school due to their graphic sexual content. If you had told me then that in 2021, it would be secular liberal democrats pushing to ban books, I would have laughed in your face, but here we are, and I'm not laughing.
