Somewhere, some place along the way, someone got the idea to defend G/N/S against the trolls by saying, «We don't use it to classify actual gamers.»

Bullshit. *I* use it to classify gamers. G/N/S is about role-playing DECISIONS and PRIORITIES, and it is expressed in many ways. One of those ways is game design. Another of those ways is via a person's actual role-playing behavior.
