I don't have to answer to you or any other post-1996 bandwagoner -- I lived through the first and second Yankee "dark ages", yet still called them my team, painful as that was at the time
you're likely a frontrunner, who became a Mets fan when it was fashionable (1969 and/or 1986), only to decide it was OK to wear the interlocking white NY on navy around, say, 1994 -- and, if YOU moved to Beantown in 2004 (like I did), you'd be claiming lifelong RSNer status
