"Nation, I am on record as being a huge fan of censorship," Stephen Colbert said last night. "Of course, you wont actually find it in the record -- I had it taken out." Colbert used this to preface his thoughts on the new edition of Mark Twain's classic novel "The Adventures of Huckleberry Finn," which publisher NewSouth Books has edited significantly by replacing each instance of the 'N-word' with the word 'slave.' The expurgated edition has sparked a wave of controversy, igniting reactions from both scholars and readers who denounce the edits as unnecesary censorship.
