Long before I even knew what libertarianism or statism or any of that shit was, back when I was in about 8th grade, I recall feeling like the arbitrary-seeming local sports allegiances were ridiculous.
There was a football game coming up between Dallas and Atlanta. I was in school in suburban Atlanta. So many people were rooting for the Falcons, of course, including my step-sister and step-mother. My dad and I bet against them on the side of the Cowboys because we were quite confident that they would win. So we were rooting for Dallas. Why? Because we thought they were the better team and because we fucking had money riding on it!
When I see sports fans with admiration for a team other than one associated with where they grew up or where they're living now or whatever completely arbitrary association, I tend to be a little impressed with their thought processes. Otherwise it just looks stupid. No, not a NAP thing. They just seem stupid, and that's how my step-sister and step-mother seemed to me at that time. And they lost their money for it. But hey, rah rah, local team! Whooo!
