I'm sure you've read the stories of Huck Finn being edited to remove the 'N' word and 'Injun'. I remember we read the book out loud in class in 8th grade and being very uncomfortable whenever that word came up, so I can certainly understand why they're doing it. Is it the right thing to do though? Are we scrubbing out an ugly part of American history, and doing both the author and the young readers a disservice in the process?
While it is a fictional story, I think to pretend the word was never used is to sugar coat history and guaranteeing it is repeated.
