I know that a WDW fan message board probably isn’t the place for an in-depth discussion of the subject, but there has been a LOT of academic research and analysis of issues of race in Song of the South (the film), its source material (Joel Chandler Harris’ “Uncle Remus” stories), JCH’s source material (African American folk tales), and Disney’s interpretation of the Br’er characters.
One excellent academic journal article I’ve come across in my dissertation research:
https://www.jstor.org/stable/24898783. The author explores a couple things relevent to recent discussion in this thread:
Joel Chandler Harris appropriated the original stories. He—a pro-slavery White man—wrote in an exaggerated caricature of African American Vernacular English designed to emphasize the exotic otherness of his Black protagonist. When he wrote “Br’er,” he was making fun of Black people. Harris wrote for White families to read these tales to their children, and he tried to write the dialog such that parents could read it in ”the black accent“ (hence, “Br’er”). The author of the essay calls it “linguistic blackface.”
That was Walt’s source material for the film we all agree was terrible. And while Disney tried to extract the characters from the film and redeeming them for the ride, they do seem to retain the roots of minstrelsy and caricature of enslaved people.
Zip-a-dee-doo-dah was an attempt to remediate “Zip-****” and “Turkey in the Straw.” In the process, they created an iconic song that people love. But why go to a minstrel anthem for source material for a sound trask of a film set on a plantation? Disney went on to make the song into a classic—not only a theme for Splash Mountain, but for the Parks. Nevertheless, YouTube and clickbait articles won’t let people forget the song’s relationship to racist entertainment of the past.
This does not mean that the ride (or anyone who love it or its characters) or the song is racist! It just means that these things will always have some connection to the source material. I believe this is whey Disney has decided not to promote the film, and not to further try to remediate the characters.
For anyone interested in further reading on Harris, I recommend Hugh Keenan’s chapter, “Joel Chandler Harris and the Legitimacy of the Reteller of Folktales” in the 1992 book,
Sitting at the Feet of the Past: Retelling the North American Folktale for Children. For more about
