Glad I asked! Interesting responses, I appreciate the information shared. For the record, I never suspected actual intent to offend; yet given the historical relationship between Native Americans and European Americans, I think it is worth thinking about and maybe even challenging tradition.
I have to say that, offense or no offense, I remain perplexed by the desire to cling to the fiction ( Disney, as a couple of people put it). Yes, I grew up with the Cowboys and Indians stuff. But my boys have replaced those fantasies with the likes of Star Wars and I think it would be just as ridiculous to have scouts holding Jedi ceremonies (tho my kids would love it). And as far as suggesting that the Disney style portrayal of real live Native Americans is as harmless as the Geico cave men commercials, well, I don't know where to begin.
I beleive that knowlege and understanding of history is invaluable. I would welcome more emphasis on real history in scouting ceremonies and activities, and leave the fiction to the campout skits. Old Grey Eagle has some interesting ideas.
