For some reason, well I think know why, the Sioux people I've met talk way more. It probably depends upon how much they fought with white people *LOL* I don't mind reasonable discourse about history but too much can be depressing. I attended school during the 500th celebration of Columbus and well between the black students and indian students it was real interesting.
One thing that has always irked me is the belief that all Indians are the same. For example, the idea that all indians are liberals (groups like AIM and stuff are certainly no help in that regard)... I wont' even go into the other stereotypes ;0)
I've visited a lot of rez's over the years and a majority of the people I have spoken with have said pretty much the same thing - they just want to be left alone to live their lives. A few have said they wanted more "assistance" from the government, but the majority had a big distrust of the government.
I would love to see more American Indian outreach by the republicans - I think ti would pay off, and really eat into the left's voter fraud ;0)
