Graham, my comment was sort of tongue in cheek. What I was saying was that those who call for "unity" often have ulterior motives -- a common one being perhaps best expressed as, "Everybody get into line and follow me and do what I say!" In other words, those who want to take charge of others often call for "unity" as a way of creating a herd all marching in the same direction, and then try to take charge of the direction of the herd.
