Craig Calcaterra, whose take on the "Philly fan thing" matches mine:
Their legitimate indignation at being tarred with the Santa Claus thing has led to a curious phenomenon: every time some fan does something stupid there, Philly fans get upset when anyone points it out, even if it happened yesterday. “Yeah, sure, go ahead and say that Philly fans are obnoxious. Feel free to stereotype us. How original,” they huff, rolling their eyes. We saw this when the guy puked on that girl earlier this year. We saw it when the guy got tased. We saw it the very next night when the copycat guy jumped on the field. Point out some dumb Philly fan behavior and other Philly fans immediately play the “we’re being persecuted” card.In order words, "they pick on us whenever there's an incident!," even though incidents seem to happen every week.But you know what? Even if they don’t deserve the reputation for being awful that so many have applied to them, there is a certain brand of Philly fan that is obnoxious. Not all, of course, and not even a large number. But a subset that is unique to Philly in their poor taste and boorishness. And hey, here are some of them now!
