That's because so many Stiller fans are also hoopies. And I'd say it's a majority of them. That's why I refuse to be around them if I can at all avoid it. And I've never been to a Stillers game and never will go to one. I was offered club seats by the company I work for last year with free food and booze and turned them down. I don't want to be around that garbage.
This is a very poor take on the fan experience for a Steelers game for anyone considering going to a game in the future. The cost of going to a game is absurd but the experience is a lot of fun...infinitely better than the Pitt fan experience.
