Last time I checked mascot names having anything to do even tangentially with Native American groups/culture were being protested. Mascots like "Tribe", "Indians", "Warriors", "Braves", "Chiefs" and "Chieftains" were all on the chopping block.
There are two issues I have with this mascot madness:
1) All of these nicknames were chosen to gain honor/engender respect for the institution/team.
2) The U.S. Constitution explicitly protects our freedom of speech.
