But is it possible you've self-selected your data?
Possibly, but in this case I doubt it.
As mentioned above, we tend to remember certain behavior we find obnoxious, while completely overlooking behaviour we find completely unobjectionable.
The language is, in this case, the giveaway.
On the one hand you have people who are happy playing the games they play, who are often ignorant of the older games out there, and who don't actually harbor any ill will towards games they either a) used to enjoy, or b) never had the opportunity to play to begin with. This group is all of the non-grognards, and it stands to reason that the don't often exhibit the "anti-game-X" behaviors we're talking about.
On the other hand you have grognards, and within this group is a
sub-group of people who are (very) set in their ways, and often believe that they know best - not just for
themselves, but for all gamers. They harbor a tremendous amount of ill-will towards newer games for any number of reasons: killing sacred cows, stealing players, putting older editions out of print, being more forgiving, being less exclusive, etc. I daresay that many of them believe themselves to be the true heirs to the mythical garden of RPG, and that all the kids playing those WotC games are, as described elsewhere in this thread, "mindless sheep."
We then tend to apply patterns to the behavior, which leads us to stereotype particular groups, whether "grognards", "geeks", or whoever. Even when most members of that group are not exhibiting the behavior we find obnoxious.
It's not a matter of
most members of that group being obnoxious. It's the fact that
more members of that group act obnoxiously, proportionally, than you might find in the general population, or even the
geek population.
I have no issue with a complaint about the behavior - just with the broad brush applied to a group, in this case grognards.
I dislike explanations that go for the "All groups are equally obnoxious, you just don't recognize it in your own group," point. I'm a big fan of groups policing their own, and frankly if I were a member of the OSR I would be
furious with the conduct of some of its other members. It has a
really unflattering image with a lot of the gaming world for this very reason. Now, granted, being exclusive and insular could be part of the appeal of the group, and in that case they shouldn't give a damn what everyone else thinks of them, but I have the
sneaking suspicion (not actually a suspicion at all) that part of the point of the OSR is to expand the playerbase of old-school gaming, and in that sense they are their own worst enemies.
