In my opinion, most of the trouble of the last few months was, in fact, a war over leadership.
A new poster came on board, and through sheer number of posts and aggressive style, established himself as the leader. The fact that just about no one else wanted this kind of leader led to the hostilities.
This was a war over territory.
Now, the old leaders (at least, most of them) have left. The war is over. I'm just not sure who won.
