Michael Schwimer wants to know if he's allowed to be a NY Giants fan

He actually e-mailed this question to Grantland's Katie Baker, who published it in her mailbag:

My dad was born and raised in the heart of New York City. He is a diehard fan of the Yankees, Giants, and Knicks. Just like any other kid with a diehard New York sports fan dad, I was brainwashed from a very early age to live and die with New York sports. My dad and I bond the most over sports and going to events. We went to Lambeau Field for the 2007 NFC Championship game, and now to this Super Bowl.

Long story short, I got drafted by the Phillies, and got called up for a month and a half this past season. My love for the Yankees has disappeared but my love for the Giants and Knicks is as strong as ever. I also have fallen in love with the city of Philadelphia and truly believe they are the best baseball fans in the country. The last thing I ever want to do is lose support from these fans, but I love the Giants. So am I allowed to outwardly root for the G-MEN or do I have to keep that to myself because I happen to be employed by the Phillies?

Her answer:

"Long Story Short, I Got Drafted by the Phillies" sounds like Bill Bryson's next work of participatory journalism (which I would excitedly preorder, obviously), but I'll also accept it as a throwaway line in my first mailbag letter from a professional athlete. Hello there! Not sure if you and/or anyone else watches Sister Wives, but it had a great reality show wrinkle in time a season or so back during which they spent numerous episodes agonizing about whether or not to "go public" with their polygamy — when, clearly, they obviously already had gone public or else how would I be watching them agonize about it on a show called Sister Wives in the first place, you know? Anyway, my point is, your question kind of reminds me of Sister Wives: You're already out in the open and now there's no point in hiding it.

Sooner or later, everyone has to learn that there are two types of sports fans: those who intrinsically understand that it's unreasonable to assume any particular athlete would have grown up as a fan of their team; and those who are certain to spit things like "He stinks. He's a Giants fan, what do you expect?" in angry earnest down the road. But regardless of whom you're dealing with, it's best at this point to remain gracious in victory, because it's hard to say how long it will endure. I say this not as any sort of reverse jinx, but rather because any fan of any NFC East team knows this much to be true: No one lasts too long on top. There's as good a chance as any that the Eagles could knock the Big Blue right down to size next season. And if/when that happens, it's going to be annoying enough without a horde of I-told-you-so-ing Philly fans getting all up in your face. (Just don't wear a Giants shirt into a Wawa.)

Here's a recent and relevant precedent that you can use in your favor, if needed: The Giants' own resident salsa dancer, Victor "they're not booing, they're saying" Cruuuuuz,not only outed himself as a longtime Cowboys fan this December, he did so in the most potentially damaging way possible: by lamenting how he "was pretty upset when we lost to the Giants a couple of years back when I was in college." That's right, He used the "loyal we." The sound bite made headlines, but Giants fans were secure enough to know it really wasn't that big a deal. And after the Giants won the Super Bowl, the New York Rangers' Brian Boyle, a noted New Englander, was revealed to have obviously engaged in a pro-Patriots bet. Rangers fans understood. So you've got leverage over Philly fans in that respect: If they give you any trouble, it's just proof that they're vastly inferior to their counterparts in New York. [Redacted because these are three very dirty words that should never appear on this blog]!

What do those of you who are fans of the Philly teams across the board think? Is this cool, or should he be required to convert to the good side?
