"Canonicity II": Has Yours Changed?

[Galin]

You [William Hicklin] are of course fully right that there can not be a 'canon' since there is no true story behind - it's all fiction.

Why not canon with respect to fiction? As in "material considered to be part of a fictional universe" (American Heritage Dictionary)

That is why I do not like the name canon and canonicity for discussions like this one, but as yet nothing better had come up.

Agreed here. And I feel as if -- whether or not it's true -- that when I say "not canon" with respect to a given work, folks are possibly attaching some "negative" meaning to the characterization that I don't intend.
