I think he lost some credibility with this statement:
"I learned at an early age what Redskins fans were really like: the worst of the worst. Good for absolutely nothing. They can't be trusted. They were so ignorant they couldn't spell "class" if you spotted them the "c-l-a-s." The class and dignity that Cowboys fans always showed was foreign to Redskins fans. I mean, Richard Nixon was a Redskins fans."
"Worst of the worst"?! As if there is such a thing in pro sports fandom. Each team has as many obnoxious fans as every other one. To say that fans who follow a particular team are worse than others is absurd. Too bad for him, he had a good blog going until that.
