Let's face the facts, as much as everyone trys to make a big deal out of the costume party that is held at the Oakland-Alameda Stadium on Sundays, I think the "Raider Nation" is an over-hyped fan base.  And here are my reasons why:

Sellouts: Oakland-Alameda Stadium is the smallest stadium in the NFL, I think the capacity is somewhere around 50,000.  Yet the Raiders can't sell it out, when I bring this up the typical excuses I get from Raider fan is there are so many other things to do, and I say like what. I lived in Northern California for many years and spent a fair amount of time in Oakland playing football and other sports, and let me tell you, there is nothing to do there with the exception of eating at some overpriced restaurants and looking at a stagnet body of water known as the Bay.  Regardless, if the Raiders were committed they would be selling out that band box and not sitting at home.

General knowledge: Talk to a average Raider fan at a bar and very few of them have any clue as to football stats, players, or history of their team (Other than they won three super bowls), to me the bigger thing with average Raider fan is the look.  They want to look tough by wearing black.  So to me, Raider fans are more about image than anything else.

Like to fight: Having been to a couple of Bronco Raider games in Oakland, seems to me most Raider fans are there to try to act tough and get in fights,with either opposing fans like myself or with each other.  Which really doesn't make you tough, just a jerk off that has some issues with your self opinion, and what cracks me up is most Raider fans won't even fight you straight up, they want twenty of their buddies to cheap shot you before they will get in the mix. 

Anyways, here is a poll of the most overrated fan base:
