Well, they DID change the ride back in the 90's. So, it clearly was an issue and still is. When this came out, plenty of folks admitted the scene was awkward at best. I mean, would we fight to keep Jim Crow style animatronic slaves if they had included their depiction in the Caribbean?
At the Magic Kingdom, the chase scene was altered to show the pirates making off with various treasure as the formerly "chased" women attempt to thwart them or to show pirates chasing women for food. The "Pooped Pirate" here holds a treasure map in his lap and a magnifying glass in one hand. The woman in the barrel remains, although this time she is hiding a small treasure chest in the barrel with her. Previously, the entire scene was pirates chasing women. At the time, these changes had not been made at Disneyland Paris.
In Jason Surrell's book Pirates of the Caribbean: From The Magic Kingdom to the Movies, showwriter Francis Xavier "X" Atencio referred to these "softening" touches as "Boy Scouts of the Caribbean"
Clearly, Jim Crow slaves would cause an issue.
Let me ask you this...does your mom no longer ride Pirates out of disgust? Or if she does ride, does she close her eyes during that scene or look away? Or does she just sit quietly and let the moment pass?
