I lol'd. Support your country man, that is the point of the world cup. All the different players that play all over the world in different leagues, for different teams, with people of different nationalities come together once every four years to put aside what they normally do and play for their country's price. Would you support Brazil over America?
On a totally unrelated not, FUCK Brazil. Korea never had a chance (they scored a goal though whoa, wasn't expecting that), but I would root for anyone in a game against Brazil. Mostly just because they knocked England out of the Cup in 2002 and I'm still butthurt about it though :p
