Well, help is at hand: it appears that Richard Grayson, a Brooklyn writer and editor, has self-published “A classroom-friendly version of Mark Twain’s classic novel, with every occurrence of the N-word replaced by the word ‘hipster.’ Thanks to editor Richard Grayson, the adventures of Huckleberry Finn are now neither offensive nor uncool.”

Destroy with ridicule - always a smart move.

Updated with a link to an excellent commentary by John McIntyre

Interestingly enough one of Conrad’s best books, The Nigger of the Narcissus, 1897, was retitled for the first American edition later that year. It became The Children of the Sea “at the insistence of the publisher, Dodd, Mead and Company, that no one would buy or read a book with the word nigger in its title.” (Wikipedia).

I suspect the reasoning behind these decisions a century apart would be very different!

More revealing still is McIntyre’s footnote to the word “nigger”:

**This will be the only explicit mention in this post of that word, which I do not use myself, and do not recommend for any white people to use casually. I use it here simply to make clear what the central issue is.
