Intro to Should everyone be allowed to use the "N" word?

“Nigger” or “Nigga” which one would you rather be called Nigger or Nigga. Is there a difference between the two words? In my English class we are reading The adventures of Huckleberry Finn and in the book they mentioned the word a lot. Say for instance you were a slave would you want your master calling you a Nigger? Or maybe a racist person calling you a dirty monkey? People sometimes use the word in a racist way. Others can use it as a greeting to your friend, buddy, or hommie. Some also use it to hurt another person. If you were greeting a friend would you say it? What is the difference between Nigger and Nigga? Is there even a difference?
