Randy, you're trying way too hard.
Ha, I knew you wouldn't be able to resist. In all honesty though to me it's stupid to have multiple teams. The dedication it takes to really be a fan leaves room for only one.
The only exception I can see is a European team and an MLS team because there is no way they could ever play each other in a truly meaningful game (unless you count the Club World Cup) and you are just making an effort to support the home league in your country.
Having multiple European league teams is shameful imo.
