Retrocool: I wrote a lengthy article about "Song of the South" myself some years ago for savedisney.com - - now archived at songofthesouth.net.:
Song of the South.net - News Archives: SaveDisney.com - In Defense of Disney's Uncle Remus
"...Though the film has been labelled "insensitive" or worse... "racist"... I see it as quite the opposite: a reaffirming story of the bond between two friends that refuse to be separated by race, class, age -- a friendship that is forged and held against all odds. A tale of unity...."
The film seems more concerned about the the power of innocence and storytelling to touch the heart, unite, teach and heal (recurring Walt themes), rather than any worldly politics. Naive perhaps, but not racist.
A related article, "The Spirit of Youth":
"...Peter Pan, Song of the South, Pollyanna, The Three Lives of Thomasina, and, perhaps most memorably, Mary Poppins, all center on the concept of a distant parental figure lost in the trappings of adult society; ...propriety, power, marital problems, mourning, regret, politics, business, money... all of these "grownup" concerns were shown to distract from the pure, joyful innocence and simplicity of a child's point-of-view..."
We might discover Disneyland's Opera House could be "the Laughing Place!"
