Well Grim and SDS, I agree with you.
It's just a game and no one should ever become violent over it. That's taking it way too far.
And believe me, if I see a Packer fan becoming violent over a bad call or becoming vigilant because someone is wearing a different team's apparel, I will not be proud of their actions and I will be the first person to tell them to SHUT THE @#$% UP and mind their manners.
I say if you want to cheer for the other team, then bring your apparel, heck, bring your team's mascot and show up in force because it is only going to make the game that much better - win or lose.
Being a Packer fan, I have basked in the glory of the Championship seasons, but I also have learned how to lose like a man during the years (and there has been many) when the Pack has not been at their best.
I love our Packers, but we would be nothing if we didn't have fine teams like the Bears, Lions, and Vikings in which to do battle.
