It's a war cry.
Baseball is a competitive sport.
It does not degrade American Indians.
Do you realize that the Seminole Indian tribe in Florida endorses the use of its name and imagery with Florida State?
However, it is a sensitive topic, and some native Americans and others would disagree. The Indians' mascot is a little goofy to me and I would not use it at all. I think the Braves logo is a respectable image of an Indian warrior.
Good article on Native American iconography.
