You don't have to like it, but song of the south is a part of history. The ride takes small nods from a problematic film and turns it into a ride that very loosely relates to it. I don't think the ride scenes are problematic due to the lack of blatant racist stereotypes, even if it does take references from a film that is.
Changing the ride for the sake of changing the ride is a fine discussion to have, but when we start calling it racist, I don't agree. Nor if the ride was indeed racist would I object to it being removed.
Finally, I didn't insinuate that the ride was a representation of history, only disagreed that we should change history because we don't like the way we were back then.
