Maybe they're not. Maybe one team is totally right and the other one is totally wrong. But we will never agree on which is which. We all have our own political biases and prejudices which prevent any of us from making a sensible judgment on the matter.

And that's why it behooves all of us to act like we're all teams with different uniforms, most of the time, even when we secretly think the other guys are stupid and wrong -- only by tolerating our political differences can we have a workable society.
