Chanting "USA, USA" now deemed racist...

Just some more political correctness that I've found on the internet. Recently, after one local Texas high school basketball team beat another team, the supporters of the winning team began yelling the famous "USA, USA" chant. This occurred at the end of the match. As a result of this action, the high school of the winning team and their supporters have to apologize for their "racist" action. I guess someone forgot the fact that the United States (USA), comprises of many cultures and ethnic backgrounds.
