Not to presume to speak for native americans, but just based on what I read etc. there are some groups that voice opposition to names/mascots based on their heritage and some that don't. Apparently the Seminole tribe in Florida has supported FSU, while for example Native Americans have fought other schools-San Diego State comes to mind in that regard. I think the differences lie not with the use of names, but how the mascot is depicted.
Years ago when Stanford were the Indians, they had a rather cornball mascot and their cheerleaders were dressed as little Indian maidens.
As far as offensive logos, IMO, the Cleveland Indians logo is not the most respectful. At least they improved upon it somewhat from the cartoon used in the 40's 50's. The sad part of the misunderstanding here is that the Indians were named after a player and to honor him, who was the first native american to play in MLB. Prior to that they were the spiders.
The Braves Chief knock-A-homa was probably not the most respectful depiction of native Americans, but at least he has gone by the wayside.
The name redskins is derived from settlers buying the skins of corpses of slain native americans and that the is name of our nation's capital's football team.
Bottom line, I don't think it is just about names. It is about mascots, ceremonies etc. that go with it.
I went to a college located in a predominately african-american neighborhood. One of the fraternities was called the fijis. They'd dress their pledges in black face and have them run around campus and fraternity row as if they were "native savages". The annex building to their house was burned to the ground. Guess some of the neighbors didn't care for the depiction.
Notre Dame always gets mentioned in this, but their mascot is a leprechaun and those are fictional characters. Similarly, not too many Spartans and Trojans roaming our streets. Native americans are not fictional characters.
Perhaps you need only look to the concept of your own heritage being depicted as a cartoon mascot
Back to Notre Dame and the leprechaun, when Stanford's band brought this past the leprechaun and into the realm of actual people and presented a half time show about the potato famine, they were permanently banned from ND campus
If you Substitute any ethnic group and an attribute they are stereotyped for and put that in place of 100,000 college students doing war chants and the tomahawk chop, maybe the issue comes more into focus.
