Sharpton: Bieber Tape Shows Why Even Blacks Can’t Say ‘N Word’

Sharpton: Bieber Tape Shows Why Even Blacks Can't Say 'N Word' (TMZ)

Justin Bieber's racist song underscores that the N-word has no place in our vocabulary ... so says Al Sharpton.

Sharpton was out on the streets of New York on Wednesday when our photog asked him about the videos ... which the Rev described as "troubling." 

Sharpton said this scandal presents a "teachable moment" for Bieber and should serve as a reminder to everyone "none of us can use the N-word."

Although Sharpton seems to have forgiveness in his heart, his iPod is another story.
