are you afraid of not being politically correct? or why is the topic "ugh"-y?
the people that are most prone to becoming "elitist" in their mentality are the mentality dominant ones (Se/Si/Ne/Ni). people with these are auxiliary functions are in a gray area and will most likely see things in a more balanced light.
i'm willing to bet that there outside of people who know their MBTI type exists no N elitism, because people don't know their type, and therefore aren't proud of it. like whoever said it, it's more a detached form of "selfishness". on the other hand, S elitism manifests itself as by the book bureaucracy (at least that's how i picture it), where change is neither welcomed nor permitted.
in all honesty, i would want N elitism to be more prevalent. both to study the effects on society at large and to see what changes may come about from it. it may be "evil" looking at it from one perspective, but on the other hand, what if a greater goal could be achieved through this?
SPOILER ALERT
for those of you who haven't seen the watchmen movie.
in the final scenes of the movie, ozymandias decides to blow up entire metropolises across the globe, realizing that the blame can only be put on dr. manhattan. for as long as dr. manhattan stays away from the planet, humanity is united in world peace.
/SPOILER
i see that scene from two sides: on one hand, you have an extreme number of human causalities, for which you can mourn the loss. but on the other hand, you have attained world peace... in a time where war was lurking everywhere. to me, this demonstrates just about the most extreme scenario of N elitism. my point is that even if it is extreme, any N elitism would always serve a goal that would eventually aid mankind as a whole. look at the discovery of nuclear science, and later, the atomic bomb. we took many lives from the japanese the day the bombs dropped, yet they also served to cement the power of the technology. i'm not saying it necessarily is a good thing, i'm just saying that there are always two sides.
