Has he not noticed that writing persuasive documents is one of the cornerstones of versus debating? (Discussions of canon policy don't exactly fit well into the other cornerstones: the scientific method and application of physics and other sciences.)
Bingo, we have a winner: there's the problem confessed right there.
It's just like I said before when quoting another guy's confession:
Part of the problem might revolve around a term commonly used to describe discussions about which fictional universe would win in a war. You see, it is often called "the versus debate", the "Star Trek vs. Star Wars debate", et cetera. It would, perhaps, be better if it were called the "Star Trek vs. Star Wars rational discussion and careful analysis by a group of open-minded individuals interested in determining the Truth of the situation" . . . but that, as you can see, would be quite a mouthful.
. . . and, sadly, would be an entirely incorrect description of many of the folks involved . . .
Those who treat this as a formal debate will invariably end up approaching the following position, espoused by pro-Wars debater Ian "Kynes" Samuels:1. Debate is not a search for truth. It is an exercise in rhetoric.
2. As it is not a search for truth, positions which I do not personally agree with may be adopted to win.
3. The objective of debate is to emerge the "victor," having used superior rhetorical tecniques [sic] to gain victory.
4. Any tactic empirically effective at advancing a position should be used.
Obviously, the above concepts, while theoretically valid for crooked lawyers and other debate practitioners, are invalid in any honest inquiry. An idea is not right or wrong based on the rhetorical techniques used to defend it . . . the idea either conforms to reality, or it doesn't. Add to that the fact that, inevitably, some have concluded that incessant flaming and character assassination are empirically effective means of advancing one's position (which is true, provided that one's audience is composed of idiots), and the Star Trek vs. Star Wars discussion can take some ugly and peculiar turns.
If you're a slick salesman who can persuade someone that 2+2=5, then I'm sure that's great for you. However, that doesn't make the belief correct, not even if you believe it yourself.
Again I point to the fundamental disconnect between their worldview and my own.
