I think you guys are being a bit harsh on RBNY. Yes, the ownership and the name and the location is terrible.
But the argument that they should be called NJ is silly. There is clear precedent for teams to play in NJ, just outside NYC, to be called New York.
Also, I have no problem with their fans standing up and trying to brace against the incoming NYCFC. They have some true fans, I am sure, who love the club and want to support it. It is only natural to feel threatened by the incoming club, and try to rise up against it.
Trust me, I have no love lost for the club. But it seems to me this whole "rivalry" is a bunch of immature crybaby bullshit from both sides. RBNY fans are exaggerating the negatives of NYCFC and vice versa. Let's just focus on our club, and save the rivalry for the actual team on the field.
