I understand the change for Aladdin, because uh..it was kinda super inappropriate and I am not sure how those lines slipped by without anyone going: "Hey is it kinda racist sounding if we imply Arabic people are brutal and mean?" but the Pocahontas lines weren't changed to be less racist sounding.
The whole point of the segment sung by Ratcliffe is to highlight his racism and hatred of the Native American's. So I can understand that the lines are going to reflect that and you know what? Fine. He's racist and evil and mean, fine. But they didn't change his lines to be any less racist and evil and mean then they originally where. So it's kinda weird.
