Here is a video where Richard Pryor discusses his PAST use of the n-word. Pryor passed away in 2005, and this NY Times article written shortly after his death focuses a lot on a discussion of the word. This article and video may be of interest to my Temple or my Rowan students.
Especially for my Temple students, if you choose to read this article, please note how this is an opinion piece that uses the words of others to prove its point. Rather than emphasizing his own stance on the use of the word, the writer uses quotes and beliefs from others as well as facts and statistics to prove his point, to let the reader understand his opinion on the matter.
