It feels much more disturbing, though, to just silently update the language in the books to be more in line with modern sensibilities. Dahl was a man of his time, and as a general rule his books have good morals and values exhibited in them. They are perfect children's books, not afraid to dip into a little darkness or to poke fun at the adults who run the world, and that's a huge part of why they've been so successful and universally loved.
The mental attitude and sense of self-superiority it must take to feel comfortable taking the knife to something so well loved is really mind-boggling to me. I am very happy that I bought our collection of Dahl's books before this happened.
