I always saw Huck Finn in terms of family relationships. Huck has two father figures in the book, Jim, and Pap. Jim is by far the superior father, and the better human being. Jim cares more for his own family then Pap does for Huck, and leaves Huck a better person for having known him. Another aspect of the book I like is the fact that Jim is kinder, stronger, and more noble then anyone else in the book. Finally, Mark Twain is famous for his skill at capturing the way people speak. People really did use the "n" word, and removing it from Huck Fin would weaken the satire and commentary on the institution of slavery. As for Jim's superstition and speech, ANYONE, Black, White, Red, Yellow, Purple or Green with orange stripes, would be superstitious and use poor grammar if they were denied anything resembling education, and raised in a region full of similar lore. Well, that's my two cents worth. It's not much, but it's something to think about.
