Precisely your logical failure that I'm addressing: one can cheer for the U.S. national team to perform well on the international stage without falling into the intellectual tarpit that soccer is "leftist," or any other such nonsense.
Furthermore, MLS soccer (of which I am not a fan), is not some leftist conspiracy to take away your belief in God.
I'm not sure ... All those hours waiting for something to happen can do that to people ...
