One young contrarian (that's not him pictured, btw) decided to wear a Colts Joseph Addai(notes) jersey instead, and the principal, like any trusted shaper of young minds would, reacted calmly and rationally. He said to the kid, "If you like Indiana so much, why don't you go back?," and then threw him out of school for the day.
Well done, Mr. Principal. Not only do you want to control who your students can and can't root for, you're also hammering home the message that it's never okay to go against the grain. That's a healthy message for the youngsters. You will have mandated fun and participate in the administration-approved rooting activities, or you will keep your mouth shut! Now you write a letter of apology to Reggie Bush(notes), and then go home. Nothing un-American about that.
I guess the principal saw the error of his ways and he apologized, so today, all is good. The student, 17-year-old Brandon Frost, accepted the apology, and he apologized in return, though, in my irrelevant opinion, he's got nothing for which to apologize.
Hopefully, it's all behind them now, and the principal can get back to more important matters ... like getting the school's web design classes up to an acceptable level.
