We agree that this bill is stupid. However, the Stanford band was not clever, funny, or good.
I really didn't have a problem with the halftime show. What I did have an issue with was the pre-game statements the Stanford band made that basically portrayed Iowans as misogynists for supporting a football program that painted the opponent's locker room pink. The band said that Iowa was intentionally subjugating women by advancing a gender stereotype portraying women as inferior.
Thus, they put in effort to find a way to be offended, then called Iowans bigots because they found such a way to be offended. Thereafter, that same band puts on a halftime show with the sole intent to offend Iowans by advancing a class-stereotype which subjugates blue collar agricultural workers. Had the band intended for this show to be ironic, rather than hypocritical, then I could have seen some humor. However, I see no evidence that this was their intention.
The result is a pre-game and halftime performance that should be considered sophomoric and simply forgotten.
