The club don't deserve our support.
Or put another way, the best way to support the club is to stay away or make your feelings known.
This isn't just a case of being a bit crap, surely you can see that? I've supported through bad times before. It is about the continued mismanagement of the club resulting in a cliff edge decline and genuine existential threat. I have never known such a disconnect between club and fans before.
You can't just clap along as the powers that be dismantle the club.
