#BBCtrending: Is it ever OK to use the n-word?

A YouTube video called "blatant racism" has been viewed almost seven million times since it was uploaded on Tuesday.

It shows an angry woman shouting the n-word at a black man in Cheektowaga in New York state, in the US.

It's prompted fierce debate on social media about use of the word. #BBCtrending takes a look at the video, and speaks to spoken word poet Dean Atta, whose most famous poem condemns its use by the black community.
