What Does Being a Supporter at the Olympics mean?

The Olympics today is akin to modern "war". Athletes represent countries and fight for glory (usually and one would hope, without the intention of killing anyone). National pride takes front stage, sometimes above reason. You support the athlete for the reason that the athlete was born on the soil which you were born from. You wouldn't think twice about insulting another athlete from another soil. Yet, this soil is divided by nothing more than imaginary lines; imaginary lines which we, as a human race have come to create and accept without question. Lines shouldn't divide land, that's the job of the ocean.
