Revise the following paragraph to establish a clear antecedent for every pronoun that needs one.
In the summer of 2005, the NCAA banned the use of mascots that could be considered offensive to American Indians at any of their championship games. In order to understand this, it is important to consider that movies and television programs for years portrayed them as savage warriors that were feared and misunderstood. That is why some schools have chosen to use Indians as their mascot, a role typically played by wild animals or fictional beasts. You would not tolerate derogatory terms for other ethnic groups being used for school mascots. In the NCAA’s new ruling, they ask schools to eliminate mascots that may be hurtful or offensive to America’s Indian population.
