Val, the main reason Huck Finn has been controversial has nothing to do with language or grammer. It is due the content of the book. Huck helps a run away slave. Huck treats a black man as an equal. These ideas were very threatening to many people. Huck Finn was in trouble with the establishment from the time it was published. You'd think in this day and age, equality wouldn't frighten people so much, but it still does.
