This is from the Daily Mail so may possibly be taken cum grano salis. However, if it is true, it is ridiculous. The book is set in a particularly ugly time of American history, and to remove words that the right-on brigade find offensive is as ridiculous as publishing a book about the Holocaust with all references to the Nazi doctrine of racial superiority removed.
Mark Twain's classic novel Adventures of Huckleberry Finn is to be censored to remove racially insensitive terms from the text.The 1884 book has been removed from the curricula of dozens of U.S. schools due to 217 uses of the word 'n****r' and two Twain scholars plan to release an expurgated version. A new edition replaces the 'N word' with 'slave' and also expels all uses of 'injun', a derogatory reference to Native Americans.
The scholars say the new version is a bid to make the book's treatment of race more in line with 21st century values but critics say the censorship is taking political correctness too far.
