"Ideology," in a game, is based almost entirely on the mechanics, with a slight input from personal style. That's it, folks. Every game has a governing set of principles that all skilled players must adhere to, or they lose. You can't play a game of, say, chess, and decide your "ideology" prefers knights to queens, make decisions based on that ideology, and expect to win. And most people play games to win.
Actually, I think this is about something different. It's about game players vs non-game players (and role playing games aren't "games" in the traditional sense, as they aren't competitive, and there are no metrics). Any game player is going to dismiss this whole "debate" as silly, because it is.
