Speaking as a lapsed footie fan, footie as a game is fundamentally good. You put kids in an open area together, they like to kick a ball around. It costs nothing. As the skill levels increase, the game has an intrinsic beauty that couples individual skills with team tactics. That's why it's so popular around the world.
One of the aspects of footie I find bizarre relates to the obligatory hatred between certain groups of fans. For eg, as a Citeh fan, I was supposed to hate Man U, Liverpool, Leeds whatever. But then when watching England, all this hatred is put to the side so that fans can collectively hate the Germans, etc etc.
I know plenty of otherwise intelligent people who know what's right and wrong, racism not to be tolerated blah blah blah, then introduce the concept of footie and it's ok to hate Leeds, Mancs, Scousers, Cockneys, whatever.
Jason Mountford does a good routine on this. It's bonkers.
