This is a really difficult one for me. I do 100% agree that adult classics should remain as they are, and we should view these through the lens of historical context. Keeping those classics as they are allows us to analyse them and see how views have changed - sometimes we need to know how bad things were so we can learn from our mistakes. But I think it’s also important that for young adults, these works should be studied in a classroom so there’s someone there to explain the uncomfortable parts.
The difficulty comes with books aimed at very young audiences, like Roald Dahl novels. Kids may not always have the necessary support or understanding of the context. So I’m inclined to agree with Wilson here with regards to kids books, but it’s a bit of a grey area for me.
*Her 2005 novel is pretty worrying though. As the other commenter mentioned, the subject matter was inappropriate even at the time. It doesn’t sound like the book tackles the consequences of what happens either.
