I find your descriptions of "open" and "insular" to colour the discussion.
I chose "open" in the sense that the traits I associated to that mindset are displayed by those most likely to see the New Eden setting as an
open source project (regardless of CCP's rights to the IP) or as something that is
open to interpretation. I chose "insular" to describe the mindset that PF is
insulated (although not isolated) from player opinions and actions. It is perfectly reasonable for someone to be "open-minded" and yet prefer a play style that fits more with my description of "insular". If you have a problem with the words "insular" or "closed", I don't really know what I can do for you. Those are the most appropriate English words I know to describe what I am attempting to describe.
Other people make things up to support whatever point they are intending to make. I am uneasy about that.
Some people do and about that I would also be uneasy. And still,
some people make things up because it is fun to do so. "Making things up", an activity into which worldbuilding and creative reinterpretation of the PF fall, is not exclusively the domain of those who are trying to "win". I've made up a great number of things having to do with New Eden, but I don't bring them out in order to try and prove my characters "right" in RP. I do it because it is intellectually stimulating, constructive, and entertaining for other players.
