I agree with all of the above and especially that booing teams shows no class.
I posted a similar message in the "Let's start a new tradition" thread.
I only get to a couple of games each year as I live out of state but when I hear fans around me booing the other team, I say something. You should see the amazed look on their faces. They usually do stop but I think they feel like I am "weird" for saying anything.
These teams that we boo are young men, 18-22, that for the most part are doing positive things with their lives. Even if there is nothing wrong with booing, I think it shows no class on our part. Being a fan at a game should be about celebrating our team, not being negative to other teams.
As Hawkeyes, I would like to think that we are educated, social and decent folk. IMHO, we don't need to act like some other school fans that spew hate and negativism.
I do think that most Iowa fans are Good People and if WE just begin to comment to anyone we see booing, we can stop this Un-Iowa behavior.
