Should The "N" Word Be Used In Books?

In my opinion I think we should take into account the impact it could have on the readers. If you take it out of books and replace it with a less derogatory term, then how will kids know about the true history of slavery. It's one of those questions you ask when you are uncertain of things. Should I keep this word in books to tell the true history or should I take it out because it might offend some people. I believe that the "N" word should be taken out of books that will be used for grades K-8th grade. The level of maturity is quite low during those grades. Once they reach high school, they should be mature enough to be able to handle the book without any censorship.
