Some people believe that some of Mark Twain's writings such as The Adventures of Huckleberry Finn should be banned because they use words such as "nigger."
Twain doesn't use the word "nigger" to be racist. He uses it because it was used in everyday conversation as a reference to African Americans during the period that the book takes place. The book takes place in the 1800s the time period in which Twain lived. If you've read any of Twain's books you would know that all his books are full of satire. If Twain lied about how the past (his present) was, all of his books would suck and no one would read them.
If you think The Adventures of Huckleberry Finn should be banned just because it presents truthful opinions and words used during the time period I suggest you stay away from any honest non-fiction history books because you wouldn't like them either.
Twain didn't just base the story off of nothing, he based them off of actual history.
The United States' whole system of government is based off a little piece of writing called the Constitution of the United States of America. A part of the constitution is the Bill of Rights, which clearly states in the first amendment that people under the United States government have the freedom of speech and the freedom of the press. This means that anyone can write whatever they feel like and there's nothing you can do about it.
Anyone who thinks that books should be banned just because of the material that they present and the possibility that that material might bother some people might like, Fahrenheit 451 by Ray Bradbury.
