"
Colleges and universities may adopt any mascot that they wish, as that is an institutional matter," said Walter Harrison, chair of the Executive Committee and president at the University of Hartford. "But as a national association, we believe that mascots, nicknames or images deemed hostile or abusive in terms of race, ethnicity or national origin should not be visible at the championship events that we control."
And there you have it.
"events that we control" Those in control get to make the rules. If you don't like it, take your ball and go home. Just how does a Native American depicted from centuries back relate to something as trivial as kids playing games with balls anyway?
I guess if we can destroy their way of life, steal their land and renege on treaties, then we can use their likeness how ever we see fit.
OK, I'm ready for my beating.
