Firstly, if they didn't care about City why would they come on here straight after the game to vent. Just because it isn't in a way that's to your liking doesn't mean their support should be questioned.
People have the right to put their point across as they see fit as long as it breaks no rules on here. You're as well within your right to disagree with it. I personally don't think they should go and support another team though. There has been years of that. The more the merrier down the City for me.
You say I have no idea. If we're being truthful neither do you unless you're going through our database with a clip board.
