There are many around the world that believe that Mark Twain's book, Huckleberry Finn should be banned. They cite reasons such as racism, use of the n- word, as well as antiquated views of women and men. However, these people, while entitled to their opinions, have most likely never read the book or they would see that it is still as germaine, in many ways, today as it was then...maybe even more so.
For one thing, the main character, or one of the main characters is Jim, a black man. He is the one that Huckleberry trusts, looks up to, and considers his friend (during a time where black and white were not supposed to 'mix' or be on equal footing). In addition, it illustrates that bad people come in all shapes, sizes, and colors....not just African American. During its time this book was very controversial for that very reason.
Lastly, it discusses what the feeling and action of 'freedom' really is and what it truly means for a person to be free. Huckleberry realizes that money and family don't really mean freedom to him, but to Jim, family is everything. Huck learns a great deal from Jim about being human, and it is those lessons that Huck learns, that the reader also learns.
