I just got back from a Florida vacation and took in the Boston in Tampa game. My family, including 2 girls ages 8 and 6 were sitting in section 106 if that matters at all. Obviously neither team is Canadian. Also, with the accents, it was clear they were American. There was a group of 4 people in the seats directly behind us, mid 30s I guess. All 4 were drinking all game and wasted before the 1st period was 1/2 over. The 1 guy in particular was screaming and swearing the entire game. A few times his girlfriend(or wife) whispered to him to cool it since there were small kids around, as there were other small kids close to us too. He would say sorry and do it again a play or 2 in the game later. My wife turned around and politely told him he can yell and scream all he wants, but cool it on the swearing. I too turned around and asked him to stop the swearing. He said sorry again and that he loved his Bruins and was getting too wrapped up in the game. Security did nothing. I know they knew about it as one of the times I turned around, I looked up at security, shook my head, and they acknowleged seeing his actions. Now, I had quite a bit of size on the guy and with my "background" could have really taught him a lesson in life, but would never go down that road in front of my kids and it wouldn't have really accomplished much anyway.
My point in all of this is that ignorance and disrespect can come from anywhere. Any time, even in a non-sporting event, there is bound to be trouble when the crowd is big enough and passion is involved. Alcohol is usually, but not always involved. Think of it as a village at each game. Every village has it's share of idiots. While I hated the swearing environment for my kids that game, I won't let it alter my thoughts of my experience, outside of those 4 people and Tampa security. Unfortunately though, when I do think back about the game, that crowd stuff is the first thing that pops into my head and not the game itself or the arena. I guess it is just human nature to remember the few idiots the most.
