Yes, I am a Packer Fan

Today the Green Bay Packer's lost to the Minnesota Vikings...bummer. But the emotions ran high even before the game as Brett Farve played at Lambeau Field for the first time since he switched teams. Many fans had mixed feelings, including my sister whose a die-hard packer fan...but she kinda wanted to see good ol' Brett do well. From the time Farve ran on the field until the start of the first quarter boos from the stands filled the stadium. One fan said "personally I'm booing while I'm crying", while others had signs that said: "We'll Never Forget You, Brent" and a banner flying behind a plane reading "Retire 4 Good". He is a hall of fame legend and no doubt that legend was built on the Green Bay Packers. I mean he's an ingredible player, I guess you can be a fan of him and your team. But I need a question so I guess you could ask where should your allegeance lie? With the team or the star? Lucky for the fans those signs are protected under free speech, is it possible though that someone crosses the line? (its land of the cheese heads...I'm sure someone could think of a sign that gets them kicked out).
