That's fine, but the American Indian nation is still overwhelmingly against having its identity appropriated for sports mascot use and it is inappropriate and insensitive for any of us to argue with them as pedestrians - especially when our real motivation is our own sports fandom.

A small minority of American Indians find the name offensive:

Ninety percent of American Indians say the name Washington Redskins does not offend them, according to a new national survey.
Only 9 percent of polled Indians say they find the name of Washington's professional football team "offensive," according to the results of the University of Pennsylvania's National Annenberg Election Survey. The other 1 percent did not respond.

Small minorities get upset. I've heard people complain about UPS's "what can brown do for you" slogan. People like the have a reason to complain, but saying that a whole race overwhelmingly feels that way is out and out wrong.

I feel this is also a good point:

How can it be that communities honor such groups as patriots, padres, angels, packers, rangers, and Forty-Niners by naming beloved teams after them, but when they name their teams after ethnic groups it constitutes an insult?
