Be honest, San Diego vs. Seattle is like North Carolina vs. Duke, Dodgers v. Giants, Yankees v. Red Sox, UCLA v. USC, USA v. USSR, or Spy vs. Spy.
The hatred is palpable.
Allow me to give you a sample, just to raise your ire:
Seattle was a city founded on a belief of synergy amongst those inhabiting their corner of the U.S. and would ultimately choose a team mascot that reflected that particular ethos. In contrast San Diego opted for a mascot that was in conflict with the indigenous people of their corner of the U.S.If that doesn't boil your blood, then you're just not a red-blooded-sports-fan.
