Me? I think it's appalling. Roald Dahl was who he was, a man of his time. He was a very talented writer of stories both for adults (which is how I encountered him as a teenager, how can you not love Lamb to the Slaughter, the first one I read?) and for children (my daughter loved his books). In many ways he was not a very nice man but that's by the by. If we took away all the creative works produced by deeply unpleasant people (not naming names here) the world would be a much poorer place.
I'm with Philip Pullman, here, as reported from R4 this morning. Rather than bowdlerise Dahl's books, simply let them fade away as new children's authors, more in tune with today's children and their world, emerge.
