Despite Tarantino being bashed by Spike Lee in a video interview and on Twitter, Nas has come forth to side with Tarantino on the subject of his newest film, Django, and the racist content within it.  Nas in the past initially tried to release his 2008 album, Untitled, with the title of the N-word.  He understands what it's like to be an artist and have a specific vision and desire to express that vision to the fullest, so he isn't sure why Spike or anyone else hating would be so shocked that Tarantino put so much raw content in the film that revolves around racism.

"I didn't see what the big fuss was about.  It's a movie, movies by [Tarantino], why should we be surprised if the movie is raw? ... He's one of the greatest filmmakers of our generation, and we don't go there to see anything less than rawness. He's an artist, and artists have to express themselves."
