Well, it is an interesting point after all, to think of how older works should be viewed. I've known of school systems in the U.S.A. that have banned works by Mark Twain from their libraries because the books contain the word nigger in several places. I personally don't think that is a justified practice, since at the time it was common speak in the States to refer to blacks that way. It doesn't do a book justice to judge it by modern standards.
