The arguments on this thread seem pretty one sided...
Honestly, there are a billion themes, ideas, that Disney can use to incorporate into the parks and the resorts. While I can understand the interest in old New Orleans that came from the old guard at Disney back in the 60s when New Orleans square was unveiled, I think that continuing this romanticism of the old South is not needed. I love Splash Mountain, New Orleans Square (DL) and I do think Port Orleans is a beautiful resort (my favorite moderate, at that) But any more theming around the old South would be overdoing it and pushing the limit. There are things that happened during these times that simply do not sit well with certain people, especially African Americans. No white person could truly know what it is to have these things as a part of their heritage, and we can at least be respectful.
Consider that this is an opinion of a white male who loves Traditional New Orleans style music.
