That sure looks like a thinly-veiled edition war thread to me. But hey, I'm not a moderator. What do I know?
The thing you don't know is that all versions of D&D have been, in this language, heavily gamist. So, knocking simulationism or narrativism is not knocking a particular edition, as no edition of D&D has been either.
Do not confuse "edition war" with "game-style war". They aren't the same thing.
