Maybe you'll understand it if I put it this way:
We Iowans were guests of the Rose Bowl, traditionally the most prestigious and classy bowl game there is. We traveled a vast distance, at great expense, to be a part of the Rose Bowl experience, only to be insulted by a juvenile performance by the opposing team;s "band", complete with offensive regional stereotypes.
I'm actually not mad at the Stanford Band--they are children, too young and stupid to apparently know what's appropriate.
No, I am mad at a) the Rose Bowl for allowing their event to be tarnished and their guests from Iowa to be insulted by that band's antics, and b) the Stanford administration for allowing a band THAT THEY BANNED FROM TRAVELING to participate in the Rose Bowl festivities and insult an opposing fanbase with cheap regional stereotypes, which may have been a surprise to many of us but certainly would NOT have been a surprise to the Stanford administration. I thought their show was stupid, with only a couple of funny lines in it, but I was not all that personally offended. But crap, you should've seen the people around me in the stands, they were livid, thousands of them who came all the way from Iowa only to be insulted by a pack of children behaving like fools.
I tell you--if you treated your guests the way the Rose Bowl treated we Iowans, and the way the Stanford administration allowed us to be treated by their band, you'd be pretty unpopular in a pretty big hurry.
