Is this a serious conversation? Really? We are worried about the feelings of sports fans now? I mean yeah I am not classless in my behavior, but I truly enjoy the destruction of everyone we are playing. Fans included.
I do think there is never a reason to be classless and go overboard with this either. Which I have seen plenty of at any sporting event I have attended. I remember Bills in Denver years ago and the fans behind me yelling racist crap to some bills fans. My wife started chewing them out. I was like omg I have to get into a fight now.
