Even the people who seem to be in favor of it all seem to be talking about how they’ll write going forward.
With that said, editing older works to fit different contexts isn’t new at all. I remember reading my grandmother’s collection of Reader’s Digest Condensed Books, and cable companies routinely overdub curse words in movies and cut out sex scenes. Different edits for different audiences. It’s weird (it’s not weird) how we only start getting pissy about it when it comes to editing out slurs and stuff.
I don’t think anyone’s arguing for completely banning books that use shitty stereotypes and nasty racial language. The “unabridged” versions, much like the “theatrical releases” of movies, aren’t being thrown into a giant shredder. If someone wants to read an anti-semetic rant by Dahl, it’s out there. But we’ve never once at any point in the past gave two shits about editing content to make different editions for different people, and I haven’t heard an argument about why we should care when it comes to this specific version of the practice.
