It's the fact that it's not really applicable given the united of today (if that makes sense).
Of course it's fucking applicable. It reminds you cunts were you came from and it annoys you at the same time. I seriously doubt that it not being "applicable" is your real beef. You'd rather we call you something else, something which alludes to your clubs despicable behaviour in commercialising and profiting from a disaster. If we called you that you could all get on your high horses and cry about how horrible those City fans are.
