As I have posted a few times, I am a fan of multiple teams. In football, I've always liked the Bengals first, Colts second. In baseball it's Reds, and then the Red Sox.
I have a co-worker grilling me about this, saying that I am not a "true fan" if I root for more than one team, especially if the other team is more successful. Also, it is apparently against the rules to root for a football team in the same conference or baseball team in the same league.
Where do you guys fall on this?
Am I forced to pick just one team from each sport? Are fans allowed to switch their loyalty over the years?
Or, is it okay to root for more than one team?
What obligations, if any, do the organizations have to their fans, or should they expect blind loyalty?
