You're missing the point entirely. It's about behavior, not how good you are. I'm a Steelers fan. I don't like Cleveland fans. They don't challenge the Steelers ever. But you go there for a game, you risk having beer poured on you, being cursed at non stop, or inadvertently involved in a dust up.
And do Penn State fans act like clowns occasionally? Sure, and that makes me angrier than when other fans do it.
It's more than just a few students. It takes more than that to have the chants picked up in a radio broadcast.
But I'm more than happy to stop the "Rutgers bashing". I just wanted to clarify what brought it on, since you seemed confused about that.
