Should Schools teach about the "N" Word?

My town in New Jersey is one of the most diverse in the state, and we have the privalege of taking an African American History class. It is a very relaxed class work wise with arguably the best teacher in the school. The class is completely integrated with hispanic, white, and black students. We have discussed the word on numerous occasions and watch films such as A Time to Kill (great film if you haven't seen it already). Although, I would say probabaly the whole class already knew the history of the word ******... it is still something that should be discussed in schools and the issues that surround it such as why black people can say it and think its cool but if a white person ever said it to a black person, there would be a fight. African American history hits the topics most history classes don't and I have probably learned more things in that class than any other class I have taken in high school.
