My main point was that I see stories about crazy fans in other cities doing horrible shit, and I know that Philly would get absolutely crucified if the same thing happened here, but it gets almost immediately forgotten. Meanwhile the national media constantly brings up a complete nothingburger that happened decades ago as if it means anything at all today. It's a self-fulfilling prophecy: "Everyone knows that Philly fans are crazy, so we'll keep repeating that Philly fans are crazy, while conveniently ignoring the fact that there are crazy fans doing crazy shit everywhere." It starts to wear on you.
I mean hell, Bills fans literally jump through tables before their games, and everyone considers that endearing and gives them a cutesy nickname for it? That's bullshit.
