By now you have probably seen, or at least heard, of the massive amount of asinine behavior that went down in the stands, parking lot, and basically everywhere around Candlestick Park on the day the Raiders and 49ers squared off for their annual preseason match.

The Police alone tossed 70 folks for behavior-related reasons, lord only knows how many more the staff security took out, and there were 90 calls for medical services. 90!

But here is the kicker. When you heard this went down, when you saw the video, were you surprised? Were you shocked? Or did you without hesitating just shrug and think, "well I guess Raider fan just went Raider fan."

Don't feel bad, that's what most of us did because that's the culture of Raider Nation.

It's not some misguided stereotype. It's not some myth conjured up by an opponent. No, it's no accident that Raider fan has become the poster child for the "bad fan," in fact it actually took many hours of face painting and super gluing spikes and barbs onto shoulder pads to achieve. Plenty of coin was dropped in this effort as well, I mean a good Darth Vader mask will run you at least a couple Andrew Jacksons. You truly do reap what you sow and incidents, such as what happened over the weekend, are just the fruits of Raider fans labor in this sense.

It's a lot like the kids who went "goth" in high school. You remember that fad. All black outfits, tons of make up, and a conscious effort to appear as though you'd just pounded three bottles of cough syrup. It was an all-out effort to seem creepy. But call one of those folks out for being a vampire -- granted this was back went vampires weren't the epicenter for sexy -- and they would flip out. "What! How dare you call me that and say I drink blood!"

Wait a second. Didn't you just paint your lips to make them look blood-stained? Aren't you the one hissing at people walking down the hall? And seriously, you are wearing fake fangs. You're right, I'm stereotyping you. I'm sure there are plenty of scientists and lawyers out there all zombied up. My mistake. 

Like it or not the image you put off dictates people's perception of you and, like it or not, perception is reality.

Raider fans of the past spent years building the public's perception of them as the baddest fans around and it seems today's fan feels the need to live up to that. To prove himself worth of the Vader mask by doing whatever it takes to keep that biker gang-esque reputation the fan base has.

This is why when something as awful and appalling as what happened this weekend goes down, don't get upset if all we do is shake our heads in disgust.

Scratch that. Nevermind. You won't get upset. That's exactly the reaction you've wanted from us all along.
