Censored Huck Finn - Good or Bad?

I'm mentioning this in passing on my blog's morning reads roundup tomorrow, but I thought it would be interesting to get the 20SB opinions on this:

NewSouth Books is releasing a new edition of Mark Twain's Adventures of Huckleberry Finn with the "N-Word" taken out. Is this a good or bad move? Are the editors erasing history or simply blurring out a dirty word?

Personally, I think there's a place for this version amongst extremely young readers who aren't ready to discuss the complex history of racial slurs, but I think high school students should still be taught the original version since it shows a time period and characters with all of their flaws. Sanitizing old texts, to me, is a way of ignoring historical problems instead of acknowledging and discussing them.

Any thoughts?
