Ted, I'm a Mets fan that roots for the Yankees most of the time but I've only been a true Mets fan since the Dodgers broke my heart too many times, so I don't really count. I would say the main reason why Mets fans hate the Yankees is due to the perceived arrogance of Yankee fans. Apparently Mets fans find it hilarious that Yankee fans think their team is entitled. I don't know where Mets fans get that thinking but I'm pretty sure that's the explanation.
