When one editor sees another not as human but as sub-human, intrinsically and irreversibly, such a dialogue, though it might find formal expression, is a caricature by any stretch.
The hardest thing with Wikipedia is to realize that two editors with diametrically opposite views both still are humans, and still can be reasonable people. Denying that your opponent is also human is a grave error and leads to lots of bad things happening in the world.
For an example of a well-behaved, NPOV-writing nazi (albeit a convert) see Spandau: The Secret Diaries by Albert Speer.
