It is pretty bad at every live event these days. Combination of the internet age where people feel like they can pop off and spout bullshit with no repercussions mixed with a complete lack of self control. I am a happy drunk, last thing I want to do is throw or eat punches when I am there to have a good time and watch a game or whatever. Would never take my kids to an NFL game. When I do go, I make sure to be super cool to those around me, no matter what jersey they are wearing. A two minute conversation with an opposing fan about their team before the game goes a long way. And if shit goes down, go find a broom closet to hide in, right Balls?
