I would think that as a Phillies fan you'd at least try to support Cliff Lee for the Cy Young even though you know it'd never happen.
Also, I wasn't aware that anyone hated Mets fans. Yankees, sure, Red Sox, of course, but Mets? They're so harmless.
Anybody related to the Phillies hates anybody related to the Mets and vice versa. Such is the way of nature. As for Lee, it certainly was an interesting and unlucky year for him. I'm sure Cole Hamels will get some odd Cy Young votes here and there. It just shows how much the Cy Young award really isn't about overall pitching performance. Lee and Hamels have very similar numbers outside of W-L record. I think awards voters are getting better about forgetting traditional (read: useless) stats, though. King Felix winning the Cy two years ago (with like 11 wins vs CC Sabathia's 20?) was definitely a step in the right direction.
FYI I also hate the Yankees (my girlfriend is a huge Yankees fan, which is wonderful) and the Red Sox. There's just a special spot in the darkest place of my soul for the Mets. For one, the two teams have a long history of never being good at the same time. One has usually been utterly devastated by the other at any given point in time. Both franchises have long long periods of utter suckitude anyway, so there's some type of commiseration between the teams. Somehow that commiseration ends up turning into more pleasure when the other team sucks. My team may have completely fallen apart this year, but I can take comfort knowing that we beat the Mets. It makes following a 102 win season with this load of fail a little easier to swallow.
