Dr Sarah Churchwell, a lecturer on American literature, told the BBC that it made a mockery of the story.

"It's about a boy growing up a racist in a racist society who learns to reject that racism, and it makes no sense if the book isn't racist," she told BBC World Service's Newshour programme.

This editing/sanitising crap is for people who think uttering the word makes you a racist. For example if you said: "I don't think anyone should call another person a n_____." then you're racist for the simple fact you uttered it, even though you were condemning it. It's called CONTEXT. It's should not be a difficult concept.
