They do have to care about it, because it affects them. If people were doing things to offend you, wouldn't you be mad about it?

You don't know a member of that tribe was in the costume. That was a complete assumption.

First of all, we aren't talking about African Americans. And second, of course Indians define themselves as warriors, but mascots and teams might not show that.

You don't have any evidence that the Indians like it. They might think the dance is offensive and stereotypical, as a lot of other tribes do.

Well, it doesn't really matter that you think they are honorable, because you aren't part of a tribe that is a mascot for a school/sports team. People consider them offensive because in a lot of cases they are. A lot of times, the teams create stereotypes about the tribe.

Not all tribes are proud to have their tribe/race as the mascot of schools and sports teams. And in your evidence, the man also said that because of the mascot they are suggesting that his tribe is "war like and destroys us all." I am sure that that isn't a message they intend to get out.

Yes, I agree that they are trying to, but in most cases people find the fact that they are being put in the category as sports teams mascots as well as animals offensive.

To most people in that category, the mascots are offensive for many reasons, such as that they are mascots of sports teams as well as animals, and they do not like being put in that category, they want to be treated as people.

Another fact that shows schools deliver stereotypes is that according to the article "Arab-Americans Cry Foul over California High School Mascot", people and mascots dress in stereotypical clothes and/or do stereotypical things that people are offended by, because they are false in some way.

I think cultural mascots at schools are bad, because to most people that have a relation to the mascots take it as offensive. Schools deliver stereotypes to the students that could offend certain people. For example, from the article "Honor or Insult?" it states that "...they show American Indian Culture in a cartoonish way."
