Well i'm that much into football/socer either, but i acknowledge it purely as a sporting event. It's not about race, not about where you live (country). Facts are facts. There is no other sporting event on earth that can command more viewing audience than Worldcup football. Worldcup football is respected and loved by all walks of live, all colors of skin, all cultures and it even is politically and non politcally induced. It may not be as popular in one country than in another, but one country (or even a few), unfortunately don't make up the world.
That said i don't believe in the US, there is any sporting event bigger than the Superbowl.
