100% agree with the Enid Blyton take. I loved Blyton's books as a kid, to the point I actually developed a British-esque accent from reading them so much (I'm Australian). But if I had children, I would not read those books to them as they are. They're full of racist, sexist and generally outdated language, and were written by someone who was considered overly conservative for the 1930s!!
As long as the original books exist somewhere, I don't really think it matters if we give a cleaned up version to modern kids.
