Another Huck Finn Opinion

This week in class, and in the news, there has been a lot of talk about Huckleberry Finn and whether the word "nigger" should be removed/replaced. There have been a lot of opinions floating around, and even Family Guy poked fun at the censorship of the N-word. Publishing companies wish to remove this word in order to cover up a "shameful" part of our history. They also believe that the removal of this word will encourage younger readers to pick up this book.
Many people believe this censorship is a negative change; with the removal of such words, we lose a part of the United States history, be it shameful or not. I believe that the excessive use of the N-word is necessary for the reader to fully understand those times. If and when racial slurs and stereotypes are censored, we miss a part of the original story's intentions.

But censorship has not been limited to Huckleberry Finn. I have witnessed numerous incidents of censorship of the "racially offensive."  Just a few days ago, I was watching "O Brother Where Art Thou," and was enjoying my favorite scene: The brothers singing A Man of Constant Sorrow. After the scene, one of the brothers walks up to a presumably rich, white man and tells him how he made money singing a song. I remember from when I first saw the film that the man calls him a "dumb cracker," but when I saw it on TLC, they replaced that phrase with "dumb cow." I see how the term "cracker" is offensive, but with the censored version, I was left with a different interpretation of the character's personality.

While the latter example is not nearly as extreme, there is still a case to be made to keep it uncensored. Have you noticed any censorships lately?
