Mark Twain and the "N' word.

I never really liked reading stories that are hard to read, but Mark Twain's Adventures of Huckleberry Fin was really good. The dialect was sometimes hard to read, but it made the book so much better, being written in their dialect instead of ours. Now people are saying that Mark Twain uses the "N" word to much and they want to take it out. I feel that this would be ruining a classic novel. Back then, that is how people spoke. It may be defensive now, but people have to realize that, that is how they spoke and it is just a novel. Mark Twain used dialect to distinguish what kind of people they were. The less educated had a different dialect and you could tell. I feel that if you were to change the dialect it would take it away. What do you think?
