As a wannabe Southern boy, I'm a big LSU fan. I live in San Diego. I am a distinct minority. On college game days, I see lots and lots of people in SDSU gear. If I got offended at that, I'd go see a therapist, I wouldn't demand everyone else change to be more "inclusive." This whole objection to Christmas is idiocy.
Counter argument 1: Religion is different! Think of how the atheists feel.
Rebuttal: The atheists think it's all fairy tales anyway. The thought that I'd object to fairy tales is similarly stupid.
Counter argument 2: Religion is different! Think of how the Jews or Muslims feel!
Rebuttal: A college football game lasts 3 hours, not including tailgating. A religious service is typically an hour or so. Most people don't even go to their services every week. I'd say college football is a bigger deal than religion. Further, it's not uncommon to see drunken fights in the stands at a game. That's pretty uncommon in church. It looks like college football engenders more passion than religion.
SDSU gear needs to be restricted to college-football-free-speech-zones. After this weekend's loss to Boise State, I might find a lot of support for that idea.
