There is a version of Huck Finn with the word "nigger" removed being released. These are my thoughts on this.
I don't agree with using the n word, but I also do not think that it should be eradicated from books such as Huck Finn. The historical use of the word should be explained to students, as should the reason using such a word is wrong. If we erase our history, we erase the lessons it teaches us.
