People who think this movie is racist....
should watch DW Griffith's Birth of a Nation. That movie features blacks acting like buffoons and sexual predators and portrays them as power-hungry, uncivilized "negroes" who want to overrun the country. There is a scene in the film that shows the House of Representatives being overrun with blacks who are portrayed as uneducated and ill-mannered. They drink alcohol, eat chicken (another African-American stereotype), and take off their shoes in the building. To top it all off, many of the blacks in this film aren't really black, but are white people in blackface.
Let us compare this to Song of the South, which has all authentic African-American actors/actresses. No one acts like a buffoon or is portrayed as a sexual predator. Everyone seems to have their dignity in the film.
