If the votes were significantly more, I would think you would find some votes casted for the two extremes. I do believe these views are not shared by many though, and the results are not too far off from what the general player base of PS is thinking of the subject, though the distribution should be a lot closer to a bell curve than what the votes here (and in the Redit poll) would suggest. In my years here, I haven't found many that would not engage in some RP, even if not systematically, or who would never lapse to some OOC activity at one point or the other.
Still, greater participation would have given us more reliable results, as I understand the people who voted here are more likely to be among the current player base, which seems to be more focused on RP than grinding.
