THANK YOU, ASHERMAN!
I am full-blood Native American, 33, from the Warm Springs Reservation in Central Oregon. So far, Asherman has it...when you speak about Native Americans, you're not speaking about one set of people.
In college, I used to answer all kinds of questions about Native Americans, some of them you wouldn't believe! "Do Indians really eat dogs?" "Do Indians really chew through the umbilicle cords of their babies?" "Do Indians still live in teepees?" I'm not making fun of these questions, as they are genuine. And...uh, no. We don't eat dogs.
Man Called Horse is not a historical documentation. If you really wanted to have fun with your class and teach them something about Native Americans, try another film - one written by a Native American. Rent Smoke Signals or Pow Wow Highway. If you can get your hands on it, there's even a film featuring my own reservation, which was largely accepted by the tribal membership, Three Warriors. Even then, make sure that the kids know that what one tribe does, another tribe may do differently.
The reason fingers were chopped off in the movie is because the author wrote it into the script. Everyone in my family still has all their fingers. Hollywood has, until just recently, had great liberties with the Native American culture. That's why I was approached so many times during college with the dreaded, "How" and "Ugh" welcome. Often, what is written into a script didn't even have to pass a researcher's desk. There are several reasons for this, I believe: One, there are people out there who actually believe that there are no more Native Americans - that we're extinct. And if they're gone now, why try to be accurate now? I've met a few of these people. Two, until just recently Native Americans quite often were played by non-Indians in film. Today, Adam Beach would probably question why he was chopping off any fingers. Three, there are so many tribes on the continent, surely one of them must have done it this way. That may be true - but I've seen some pretty bad examples of this thinking.
Consider, if you would, each tribe being its own separate nation. And then realize that anywhere in the world, each nation does its own thing. Ancient Egyptians mummified their dead. Some African tribes burn their dead. Other nations seal their dead in tombs, or even eat their dead. The same goes for the nations of Native Americans. In my tribe, we ceremonially bury our dead. Another tribe - no more than twenty miles downstream from ours, wrapped their dead tightly in buck skin and laid them to rest on an island in the Columbia.
When asking why Indians or Native Americans performed a certain rite or ceremony, it's as foggy as asking why humans do a certain thing. And even then, you have to look at your source of information and consider: Is it a reliable source?
Hollywood isn't very reliable. Today, I wouldn't watch Dude, Where's My Car? and make my assumptions about caucasians on that one movie.
I commend you for including Native Americans in on your lessons! Take care!
