As bad as the decision has been to some, the board will make themselves look completely subservient if they back track now. They need to weather the storm of emotion and simply ride it out. Yes, there might be short term pain from losing memberships, but if they truly believe we are better off without him, supporters will come back when we are successful. Yes fans are upset, but they'll be back. You don't lose your passion for a club over one player being told to move on. If you do, well you probably shouldn't have been supporting the club in the first place.
This is their first major decision as a board, how weak will they look if they are too frightened by the public backlash. Supporters aren't shareholders, they have no stakes except emotion. As i said you might lose a few dollars in the short run, but you'll make them tenfold down the road if the decision is a success when the same supporters who left come back. Farah needs to go for the sake of the board. It's sad, but they can't back down now.
