to put it bluntly, If the majority though that a charge was just fine and we represented that view to the BA, would you be happy about that- the answer is probably not, so by not campaigning we allow the discussion to happen and various views to be put forward, without the possibility of upsetting those who disagree, then the like minded individuals all have the opportunity to talk amongst themselves and they can individually (or as a group away from the forum) put their case to the authority.
