Oh, this is awkward.
Ray Bradbury’s Fahrenheit 451, once the darling of every small-town activist librarian aghast at the idea of not making Tropic Of Cancer and Fear Of Flying mandatory reading for nine-year-olds, turns out to have had a few, ahem, controversial aspects to it. In particular, the book railed against a society where abortion is encouraged and children are shuttled off to anonymous daycare.
Don’t remember that part? That’s because you probably read the censored version.
