What's kinda scary is that at a time when your brethren in the Native community are so upset at being objectified and silenced, you are here vilifying their stance like their voice means squat. That's pretty much been the norm for their community since folks came from Europe.
I've stated a few times in here how I'm acutely aware of the "why" in the matter regarding Chief Wahoo and the name Indians compared to other non-Native Tribe fans. I have serious doubts about your connection to the native community if you can't grasp the psychological impact of being boiled-down into a caricature that random non-Native people mimic by acting "Indian", wearing head dresses, and making "war cry" sounds. Literally, all of these factions of Native tribes have been collectively identified as northwest white plains natives and their integration into pop-culture following Littlebig Horn has been collectively reinforcing the notion that they are just a bunch of novelty characters. This objectification does lead to psychological issues for Natives. But as you say, "it's just a few marxists!"
