What I wear to the game has a lot to do with what I think looks good that day and, quite stupidly, superstition. I wore my green F'hawks shirt throughout the football run last year because they kept winning in it. Otherwise, some games I might have opted for my old "Sioux crew" shirt (which are still cool).
If I hear a let's go Sioux chant, I'll chime in. If I hear let's go Hawks, I'll clap and yell too. I won't leave a guy/gal hanging on a Sioux yah yah either.
I do, however, reserve my booing for opposing teams, fans, referees, scores from around the country that I don't like, Bob Kelley appearances on the big board (08-12 I can't help that), any mention of rival teams, commercials I don't care for, beer prices that are too high, lines for the bathroom that are too long, 2 beer limits, when the wrong little kid wins the dance off, when a guy beats the cute college girl in the intermission/halftime/timeout challenges, and when the arena plays dumb new music. But I do not boo our team/team name.
On this note, we should bring back hissing. I've always heard of booing and hissing, but I never hear hissing. Let's hiss the heck out of people.
