Stupid asshole fans exist in every city, including Chiefs fans. I went to a Chiefs/Raiders game on Christmas day several years ago. The Chiefs won and my brother and I were hanging out at a tailgate after the game. One particular Raiders fan walked by looking pissed off so we heckled him a little. He spun around and came at me. Being a a Raiders fan I thought my life could be in danger, heh. He told us about how he'd been jumped by a group of Chiefs fans about 30 minutes earlier and they'd taken his wallet and threatened to beat his ass. He left and reported it to security but what was going to happen when the perpetrators were gone so he left and was heading back to the Adams Mark. Strangely enough that's where we were staying too... didn't know that when he walked away from us.
We ran into him in the lobby. He was still pissed... for good reason... so we invited him into the bar and took turns buying him drinks for the next few hours to try to make it up to him in some small way. He calmed down and left that night knowing all Chiefs fans weren't assholes.
These stories about how any one fanbase is really worse than any other always make me laugh. Drunk football fans are often assholes. It doesn't matter what team they root for.
