Why so bitter? You clearly watch the NFL. I don't understand the animosity - it's just a cultural thing.
I suppose if another country or league of nations was interested in forming a gridiron football league that was competitive, we would be more than happy to play a "Mega Bowl" or whatever. Until then, we'll just keep calling ourselves World Champs.
The "American Football" vs. "Real Football" debate is tired and stale anyway. There are many types of football whether its association football (called soccer by many countries - not just America), rugby football, Australian rules football, gridiron football and others. So what gives?
