The difference is sheer numbers. That's what a "mob mentality" is: perceived strength in numbers.
I can't speak for the "typical" Wings fan, but when I go out to watch a game, I don't challenge people to fights and act like a common monkey. I don't think the Wings are the end-all, be-all of sports franchises. I understand that there are up years and down years, and ultimately, I have zero interest in what happens other than 3rd party experiences. If a team bests the Wings, ****ing awesome, more power to you. I have zero control over the roster, the coaching, and ultimately, what happens on the ice.
If I were playing for the Wings, I might think differently. If I were insane, I might think differently. But I know it's a sport that I have nothing to do with, and that all I can do is cheer and hope.
Anything after that is pointless; if you think you can change things by whinging on a message board, you might want to check yourself.
