I think for everyone of those with the exception of the puking one are either no big deal or another city has done worse.
1) Booing Palin - Who cares?
2) Throwing snowballs - Broncos and Raiders fans have thrown snowballs, iceballs, and snowballs packed with batteries at players on the field.
3) Fan falling into the penalty box - Only an issue because the plexiglass broke.
4) Throwing batteries at JD Drew - See #2.
5) Sex for going to the World Series - Good for her.
6) Guy running on the field - Happens everywhere.
7) Booing McNabb - See Jets fans every single year.
8) The court room - publicity stunt for a judge with dreams of higher office, nothing more.
9) Puking incident - no excuse, but the other fans beat him up.
10) Cheering Irvin's injury - Chiefs fans cheered their own player getting injured (and they're not the first--Saints fans have done it). People didn't know to the degree Irvin was hurt and he was an asshole. That's not completely defending the action, but it's a mitigating factor.

You're just upset you didn't think of trying that...

You're really good at detecting when people are serious.

Because there are a half dozen other cities that do the same thing. It's no different from any other passionate city like New York, New Orleans, or Boston.

I like dispelling the myths.
