I can deal with Steelers fans though I would love to wipe my azz with a "terrible towel"
Washington sports fans are terrible... TERRIBLE! We've got a huge influx of arrogant Dreadskins fans, and while I hate Dallas, I don't like Redskins fans at all. Typical Washington sports fans blindly support the Redskins and Wizards but the Caps (the only good team in Washington) get no love.
But, honestly, it's the obnoxious Philadelphia fans that did me in when it comes to football. Between the Philly fans and the Redskins fans, you get an earful. They just get so erratic in any football conversation... it's like "Dude, calm down, it's just football."
NASCAR fans are the best in sports. I've never seen two NASCAR fans brawl over the outcome of a race. Football fans are, on the other hand, terrible. And we've got some of the worst of them in Washington and up in Philly.
