I also think teaching about their culture without teaching about all the atrocities is wrong. I'm not native, I have 1 native forefather a very long time ago, but isn't relevant. I don't really say this in regards to offending natives in a "liberal" sense, but I disagree with it simply because it hides a very large portion of the truth out of sight from young ones. To me, I don't really care if it doesn't offend particular natives, I wouldn't want any young one of mine learning such a serious history in a fairy tailed manner. I think epcot would be a fine place for this, and I think you could include brief histories about the various wars and decimation. Disneyland isn't the place for controversial education, let them learn about this subject somewhere else, and let them learn much more about it.
