Can't replicate the highlighted part. I have friends and coworkers that root for the blue team, and there's no hostility.
DC is clearly Philly's biggest rival; the loudmouths among their fans wish we'd care enough to hate them, but the DC and Philly players genuinely don't like one another (turncoats/mercenaries aside).
I don't know how anyone could be "cool" towards NE, I still hate their guts. Bonus points if you're a Jets fan and despise Kraft.
I ran out of likes for today.
Moving from tri-state CT to northern CT I've come to hate all massachusetts teams, but even before that I thought of the Revs as a rival; they knocked Metro out of the playoffs enough times in the 2000s.
The fact that they are owned by Kraft, one of the biggest scoundrels in sports history; I don't want them to win a single game.
