And I think you've missed the point of a lot of 'stay away' fans.
For them it's not so much about the financial cost, more the 'moral' cost. If people can't accept who is running the club, who am I, you or anyone else to tell them how they should or shouldn't show their support [or otherwise] for THEIR club??
Everyone is allowed an opinion on who should play right back, so why deny people their opinion on who is in 'chair'??
