Katt Williams -- Quentin Tarantino Has No Business Using the N-Word

In between getting out of jail and getting in the middle of a parking lot brawl, Katt Williams took the time to talk to TMZ about "Django Unchained" ... and threatened to beat the crap out of Quentin Tarantino if he gets the chance.

Williams didn't voice his opinion in a polite way like Spike Lee did. First he threatened to punch QT in the face, then told us, "Quentin Tarantino thinks he can say the N-word. But I checked with all of Ni**adom and nobody knows where he got his pass from. I hope he didn't get it from Samuel L. Jackson and Jamie Foxx cause they aren't going to help you when I see you."

When our photog tried to compare QT to Steven Spielberg (who made "Amistad" in 1997), Katt shot back, "Quentin Tarantino is no Steven Spielberg. Steven Spielberg doesn't wanna be black, Quentin Tarantino thinks he is. So when he meets a real ni**a, we'll see if he is or not."
