This 'who are the fans' argument is getting a bit boring.
Put simply, I would have to say that anyone who is boycotting the club at the moment (me included, although Crouch has made me think again), can't really call themselves fans.
However, I would say that the boycotters care about the club as much as anyone, and are staying away for what they think are decent reasons.
I wouldn't knock anyone who goes to games, I wouldn't knock anyone who is boycotting. Each to their own. But these futile arguments are getting a bit much now.
