Red Sox fans, without a doubt.
They are sadly driven by their obsession with all things Yankee. The truly sad part is that if you asked a die-hard sox fan if they would rather see a sox win or a Yankee loss, their blind hatred would choose the latter. And all this after the greatest comeback in sports history...and that still wasn't enough for them. Not used to winning, I guess, unlike many of us longtime Celts fans.
And this Yankee hatred permeates all levels of their existence. You don't see bumper stickers saying "Go Sox", but you do see a whole sh__load saying "Yankees Suck". I haven't been to NY in years, but I doubt they (NY fans) have bumper stickers that even allude to the sox, never mind validating their existence by expressing hatred for them.
Sox fans want their team to improve and be better and win, not so much to be an end desired for team's loyalty sake, but rather as a means to not allow the hated Yankees to win.
Sox fans are like spoiled brats in that they want something when they want something, irrespective of the costs or consequences of what they want. How about upstaging the Bruins on no larger a stage than the Winter Classic chanting that lovely pro-Red sox (or is that anti-Yankee, or does one truly override the other)slogan "Yankees ____". Lots of class. Top notch! Must be the Fenway environs that engender that warm feeling, huh?
There are Celtic fans in every corner of the world. Beat LA is a slogan that I was not loathe to share with any of my children growing up and I was proud to tell them about that '6er game,the first time I heard it and participated in it. "Yankees S___" embarrasses me as a Boston sports fan. But for spoiled sox fans, just as with a spoiled child, to whom the end justifies the means, it's what they want.
So to all you Sox fans out there, you can keep hoping the Yankees S____, I'll just keep hoping we BEAT LA and anyone else in the way of us getting #18. Go Cs!!
