I'm only partway through reading this thread.
PatF is prob my fave princess movie, and Tiana is my fave princess. I would *love* to see more of her in the parks, and I really hope they put her restaurant somewhere now that Reflexions isn't happening.
That being said, my brother brought up a point. Like you said, the original Br'er stories are folktales. They're based on trickster tales from Africa, and Br'er Rabbit is a folk hero (representing slaves who overcome adversity using their wits). While the Song of the South may have "problematic" elements, supposedly it is the live action parts that are controversial. The ride doesn't feature any of the live action parts (the live action parts are a vehicle for the folktales to be told). The ride focuses on the actual tales of Br'er Rabbit, which originally come from Black storytellers.
As much as I like PatF, the original story is European, recorded by the Brothers Grimm. Is there a better way to change Splash to incorporate stories with Black origins, rather than shoehorn in an IP simply because it features Black characters (forgetting that the story is European)?
