Take it from someone who works in Stratford, and finishes shortly after the final whistle on matchdays: Trying to negotiate your way through thousands of [always angrgy, regardless of the score] West Ham fans, and the westfield shoppers, is definately intimidating!
Oh, and regarding the football only being on one or two channels, it's not though, is it? Loads of other networks pump out football themed dreck for over a month. This year, the History Channel has rebranded itself "The History of Football Channel". It's been showing nothing but old games and footballer biographies for several weeks now.
Dave has hit the nail on the head. We know you guys are having fun, and the vast majority of you mean no harm. But those of us who dislike football regard the fans of the game in much the same way that non-theme park enthusiasts regard the swarms of stag parties in Blackpool! Loud, drunk, annoying, agressive, unpredictable, could turn violent at any moment...
No other sports fans intimidate the public like this. My tube commute passes Wembley. On football days it can be downright terrifying as hordes of thugs cram around you and start litteraly trying to headbutt the train windows to vent their agression. I've seen it happen. Rugby fans? Excited, maybe, but perfectly civilised at the same time.
