Not answering the question about the chanting, sound, you keep doing you mate.
Take some of your points, especially on trying to get the message out to the supporters (which I thought had been done quite effectively if people chose to listen) and a proper clear out at boardroom level and of the coaching and scouting old boys network.
Whatever is planned next, something similar or completely different, I hope that the sitters/non-protesters don't target those wanting to affect change, like they have this time - its uncalled for and frankly bizarre.
