I'm willing to particpate as people use a term--I'm a descriptive linguist, not prescriptive--but that doesn't mean I don't think the choice of terminology confuses the issue, or feel a need not to say so. And I flat out think some of the ways RPGs are operated minimizes any game elements enough that the term ends up being deceptive with them. As soon as you hear "want the mechanics to get out of the way" that's a pretty telling phrase as far as I'm concerned.
The problem is I think there's a very wide range of things called "RPGs" some of which emphasize the game element strongly, some of which either minimize it or consider it a necessary evil at best (and a few I reserve the right to question whether are games in any meaningful way), and I think applying the term broadly to all of those is probably obfuscating discussion rather than enlightening it. Not that the borders wouldn't be fuzzy anyway, but I still can't help but think we'd be better if "game" wasn't in the term we use for the hobby as a whole. But the term is what is.
Well, if we're going to proceed with the common term for the entirety of the hobby, its moot.
