yo stop acting like we are in a high school cheer squad. this situation is not at all that close to the autographs at the bbq because there, you are essentially annoying the players. in the stands your cheering, and thats what its about.
That's the kind of thing i am talking about right there. It's that entire attitude of "what are they gonna do to me?" or "you can't force me". What's wrong with just doing your part in trying to participate in a unifying effort for a night and not caring what anyone else does? If it makes someone feel better they can put the jersey back on after and go play grab ass at the bars.
you said earlier that, "its called team spirit." and no, there are PLENTY of other ways to show it. so if there are some dark shirts in the crowd, the team isnt gonna do as good? give me a break its not that big of a deal
