What people say at the arena doesn't bother me. If I don't like a chant, I just don't partake. I don't judge, don't belittle, and don't criticize because quite frankly I'm sure some of my actions are not exactly 100% super-duper nick jr copacetic. I just think it's very easy to throw stones.
If you simply don't chant what you don't like then the chants will fade. The chant in questions was in the process of fading until the team went all PC police on everyone. You hardly heard it and some fans would actually boo over it. It will take some time for cooler heads to prevail again but such is life. The team did it to itself.
Let people chant whatever the want. As long as they're not targeting specific people why should anyone really care? They paid for their ticket just like you did. I don't agree with all the chants at The Rock but I'll certainly defend everyone's right to say whatever they damn well please. And if the majority feels it's ok well, then damn, I guess it's ok until the majority changes its mind. It's the nature of the beast. If you want to kick people out that whistle it's no better than removing the goal song. If the majority sides with the whistler you will get backlash (not saying that the support for that chant is anywhere near the goal song).
Stop policing everyone (slightly hypocritical because this post is policing people by telling them they should not be policing people
). Let people do as they please and gradually the fans will police themselves. There may be a day when it's only a dozen or so people who say it. And wouldn't that be awkward?
