Griffith's "The Birth of a Nation", "I Am Not a Racist" rearranges the scenes of the classic movie and recreates its dialogues to criticize the racism in it and also in the world today.

Griffith's "The Birth of a Nation", a racist work that starts a series of events exposing the racism that still exists in the city, culminating in the recreation of the KKK.
