well, i don't want to debate anything in this thread (as opposed to the threads covering this issue) but since you asked directly I will give a short answer.
- I knew what the source material was (the film) and how it glorified and romanticized the antebellum period.
- I knew the history of the film (its sanitized presentation of the south has been problematized since the 1940's (there's a lot more that can be discussed about this, but in a different thread perhaps--especially regarding the screenwriter's revanchist presentation of joel chandler harris' text)
- I don't think Walt Disney purposely tried to make a racist film (he seemed honestly surprised and sad)
- I don't think Baxter or the other Imagineers were racist (indeed they changed the infamous tar-baby scene to a bee-hive scene on the ride). I also know they were trying to recast America Sings which heavily influenced the design choice.
I love how long the flume is, how it mixes genres (flume and run-away train style coaster), and the alternating speeds of the ride. I also wish they hadn't turned down the splash zone for pedestrians watching the ride.
