The "N" Word

I decided to write a blog about the "N" word because I hear it so often. Kids say it all the time where I work. I hear it in the locker room at the gym. I was even called that by someone I was on a date with.

Why is this word used so often and freely? How is it that a word that was used in a derogatory manner towards people of color has become a word that people of color willingly use towards themselves?

It really doesn't make sense to me. Is this word so common because people are ignorant? Is it that people lack dignity, integrity, and pride?

What is the answer? Why do people use the "N" word?
