The problem with so many of Mel Brooks, and some others, movies is that you need to have a certain level of intelligence to get it. I had to fill in some areas of history to our children before they got it. The schools have whitewashed some things we learned, and I did not believe it had happened until I started asking questions concerning why the kids did not understand some of the satire.
Worked with a friend yesterday who's sister is a teacher in South Dakota. While we had Columbus day in most of the Nation, South Dakota celebrated Native American Day. Not saying that expanding more into the changes that have come to this land since the Europeans came, but she said they did not discuss at all the European expansion for what it was. She said it has mostly been replaced with how it as effected the Native American culture.
The Bible says, "Tribe follows Tribe and Nation follows Nation" archeology and the history of human migration say the same. most migrations are westward with the most EFFICIENT society surviving, that's why the Huns may have overrun the Roman Empire but they were absorbed by western civilization, not the other way around. Native Americans may have had a commendable philosophy but they had the less efficient society so they got steamrolled by history and have been whining about it ever since.
The Lakota sniveling about the loss of "their lands" in the Dakota's, fact is those WEREN'T their lands until the Huron pushed them out of the Eastern forests with help of Champlain in the 1600's. What about the people displaced and destroyed by the Indians migrations, such as the Athabascans, maybe we should make the "Native Americans" contribute their welfare checks towards a reparation plan for THEIR memory.
