I haven't been to a game since Johnny Football's last one Vs Miss St in 2013. I am not aware of any pre-game constitution activities, it sounds kind of goofy to me.
You do just realize that EVERYONE out there who is a CFB fan has some reason to pick the team they like? Some may like the logo, or the colors, or they may have a favorite player or coach. Heck, some like the system the school runs. Some like whoever is closest to where they live. If you think about it, there's US, and then there's THEM. And if they are not with US, then they are against US, and we are against THEM. Oh, and by the way, THEM are bad. They are bad because they're not US and because I say so.
At the end of the day whatever reason any fan picks is just as valid as any other reason.
Oh, and BTW, most of the CFB fans I know consider anybody who didn't attend the school they root for a T-shirt fan.
