What's sad is that, from what I can tell, "grognard" is turning into another slang-insult for people who're unwilling/able to adapt to new aspects of gaming, and retreat into a microcosm of their antiquated game(s).
I say this mostly due to what I've seen on the grognard.txt sub-forum at SomethingAwful, which seems to exist solely for the posters there to mock anyone who exhibits a more-than-casual enjoyment of anything pre-4E.
What do you mean "turning into"?
Grognard, as far as I've ever seen the term used, has always been negative. The whole "grumbly" bit has always been in use. This isn't a new phenomenon.
