Locking a page is only a temporary solution to an edit war. It stops the current battle, of course, but a better long-term solution is to teach contributors how to write from the NPOV. I'm not saying that this is an EASY solution, obviously. I myself have struggled mightily to learn how to write neutrally, and I still fail occasionally on subjects dear to me (such as Global Warming, which Axel has reverted in flames a few times :-).
I've stepped in from time to time, as in the Eisenhower controversy, trying to show how information that veers away from the consensus can be included: usually by summarizing, creating a new article, or demoting content to an external link.
What do others think about the prospects for educating contributors to the controversial pages, on how to write from the?
