team allegiances and odd beginnings

a thread for Falcons hate on the SSF got me thinking about how ridiculous and childish some of our team allegiances can be.

I'll present my own case of LSU fandum as an example. My parents brought me to NOLA when I was in the 4th grade. At that time LSU and Tulane were nearing the end of their yearly contests. Its hard to call it a rivalry but it sparked the local interest during that week nonetheless. It sparked it enough in young kids enough to prompt the question to all your friends "who is your team" Well my dad had come here because he had been accepted into Loyola Law School. Since it was right next door to Tulane and they both had law schools, my young brain assumed some sort of competition. So peer pressure being what it is for a young one, when asked the question, I obviously couldn't be a Tulane fan so I was instantly a LSU fan.

Now I eventually ended up going there shortly and years of following do make our allegiances stronger but initially aren't all our allegiances just what we say they are?
