My anecdotes support my position, which is the fact that these concepts are nothing new, just given new, overt names. If you can actually show me how the inclusion of role in the game prevents you (as in 'no you *can't* do x, y, or z) from making the RP decisions you want, then you have a point, but they don't. If you can show me that the inclusion of role in some way created the issue of other players bossing their fellows around and trying to tell them what to do, then again, you would have a point. There is a passage in the 2e DMG about that very subject though, which illustrates that it was, in fact, a problem at some tables at some point prior to 1989.
