I am Catholic, and I am Irish, and I fight, but I still cannot stand Notre Dame.
When I was applying to schools, I didn't really consider going anywhere because of my denomination or religion. But I think about 1/4 of this country is catholic, and only 1/8 or so is baptist, yet Notre Dame has a whole hell of a lot more fans than Baylor. There are several paths to the ND bandwagon, through movies, songs, and NBC's coverage. They are the Yankees of CFB, love them or hate them. I choose the latter. As for arrogance, the USC fans were pretty bad in Pasadena, but that is the first run-in that I have had with them. The A&M fans are just falsely confident, but man they sure are one heck of an optimistic bunch, talk about finding the silver lining. As far as arrogance as a quality outside of just football, Texas has to be mentioned, as several members of our fanbase are arrogant in the fact that if our football team is not doing well, we still rely on the notioin that we are a better school, have more money, etc. than the rest of the Big XII, so we don't care, and when our football team is winning, we are even more arrogant.
But then again, it's tough not to be arrogant when you have the best fans, the best football program, the hottest chicks, the largest endowment of any public school, and the SEARS trophy....
