Just for fun, I went back and found the post:When I mentioned 10,000 moons, I was arguing that things not mentioned in canon are not proof that those things exist. Canon doesn't say that there aren't 10,000 moons. It wasn't a comparison of 1 against 10,000.
Why stop at 3? Why not have 12,000 moons fill the night sky. That would also be "compatible" with the canon of there are two moons. Heck, the 12,000 moons could bash into each others, causing some to break up and rain death and destruction down upon Oerth. Pretty sure nothing in canon says that didn't happen, so that would also be "compatible" with canon.My point is that three moons is compatible with the setting canon represented by the folio and boxed set. That someone later writes something about Oerth's moons that becomes part of canon and contradicts three moons would in no way diminish three moons' compatibility with the original canon.
So you certainly didn't seem to be "arguing that things not mentioned in canon are not proof that those things exist" - you seemed to be trying to rebut [MENTION=6787503]Hriston[/MENTION]'s contention that "three moons is compatible with the setting canon". And your refutation seems to take the rhetorical form of a reductio by appeal to extreme cases: "Why stop at 3? . . . Pretty sure nothing in canon says that [various extreme cases that you conjure up] didn't happen, so that would also be "compatible" with canon."
Now, here is the post from [MENTION=6795602]FrogReaver[/MENTION] which you described as "demonstrat[ing] that anything taken to a ridiculous extreme is bad":
So you are fine with the DM adding a new God / Goddess? A new great city in a very noticeable location that has never been mentioned before? A new moon that's never been mentioned? An extra sun? A evil emperor that has taken over most of the known world?First, additions are not changes in the way we are talking about them. Introducing NEW heroes and NEW problems, etc. doesn't change existing canon. It adds to it. Second, I've said at LEAST a dozen times that changes through game play by the players is fine.
Needless to say, I can't see any difference at all between (i) your attempt to rebut Hriston's observation that a third moon is a canon-compatible addition by inviting us to consider adding 12,000 moons, and (ii) FrogReaver's attempt to put pressure on your change/addition distinction by quering whether a hitherto-unmentioned wolrd-conquering emperor would count as a mere addition.
But I'll now leave it to you to explain how and why your rhetorical device is any different from FrogReaver's, and why it's a disingenous tactic on my part to draw the comparison.
