toonia, I find your posts to be one of the most thoughtful, and insightful contributions to this board. I rarely say anything because it'd usually be something lame along the lines of, "wow, I completely agree"....which hardly seems equivalent a response to the insights you provide.
It reads to me like it's dripping with Ni; my Ne finds it quite intriguing, while other types of Ne-tinged thoughts doesn't evoke the same awe and intrigue (in difference).
Your responses to social or relationship questions, I especially find that you don't just stick with one perspective, but offer how what you propose would be taken in by all the players involved, and even grander social implications. You see social dynamics quite globally. This leads me to think Fe.
So, I would lean more towards NiFe, although I can't be sure because there's this calm detachment, aloofness to you, and how you interact, 'hiding away in the woods', away from the cacophany of human bs. A privateness about you, which I
want to respect and not overstep, because it's subtle, strong, and self-contained, yet, not selfish or defensive. This need/want for your own space. So, it almost makes me feel like I'm defiling something poking too deep in.....so, in a way, I'm content to not know more. Yet, at the same time, this distance I feel is quite gentle and welcoming all at the same time. Weird paradox. This, for me, speaks of a very matured handle on Fe by an introvert.
So, from the little that I'm lucky to have seen on this forum, it speaks NiFe to me.
Although, I kind of like the idea of you being INFx....able to move with ease between INFP and INFJ. The ability to navigate between all those "opposing" functions with ease. A preference being moot, kinda.
