The attendance is nothing but numbers. At LEAST 1/4 of wrigleys attendance dont know a damn thing about baseball. It is where the "party" is at. After that "party" there are plenty other bars down the street to continue drinking themselves stupid.
Now are there die hard cub fans? Absolutely. There are a bunch of people that want to see them win in their lifetime since tons of other fans never got to see it.
The good ones are the ones nobody sees.
I've had several friends that were DIE hard cubs fans, could tell you every player's every stat, watched every game, went to every game they could. They're, in general, great people and good sports, as most people who closely follow ANY sport are.
Sadly, those people account for maybe 1% of cub fans. The rest, as you said, know nothing about the game, the team, or really anything else important other than getting drunk at the ballpark. Of all the cities I've been in/around the baseball scene, Chicago just seems to be the most abrasive, hostile, and just all-around mean, and it's always the dumbass know-nothing douchebag fan. I can't think of any other team's fans that ruined a dude's entire life because he tried to catch a foul ball.
My sweeping generalizations were more to get you fuckers all fired up than it was to reflect my views on all cubs fans. If I truly hated everyone who considers themselves a cub fan, I wouldn't be dating a chick who considers herself one
