being unhappy is a matter of ego, not typology. i've been told it may fade away someday, when it's not actively reinforced.
i seem idealistic but i am a shitty example for a better mankind of tomorrow, because i don't achieve anything awesome. all i do is boycott the mediocre bullshit of a conservative world. and i am too smart to think my boycott makes a difference. i know typology and stages of development. almost nobody thinks like me. so i know that i am not part of a lager trend of better discernment. i mean i AM a part of an evolutionary trend, but it's sloooooow.
so all of this reeks suspiciously of an excuse to avoid/minimize social contact. being bossed around by conservative/"stupid" people. so it's more like an expression of disgust, aversion and phobia. besides the inferiority of Fe, something about tertiary Si seems to play into the pickiness. i am rather stubborn about avoiding what i don't like. i've managed to boycott capitalism for 20 years, at a very high price of course, since i exist without real privacy and financial freedom.
i have also rejected sexual offers, because i wanted to avoid the future drama, that would have come, when either or both of us realize "it was a mistake" (or how incompatible we really are, to use my own language).
in my understanding Ti>Fe is prone to apathy and that's probably not really idealistic, certainly not moralistic, rather nihilistic. i identify with this "meme": "chaotic neutral - might save your life, might steal your car". no, i don't steal cars! but i might, lol.
Ti can't even be described as principled, because it's too flexible, it's tactical and pragmatic. but all introverted functions dislike wasting any effort for objectively functional compromises that don't pay out subjectively. Ti expects payoff in the form of gained insight or achieved optimization. for instance hanging out with a girl i don't absolutely like is totally worth it, if i can teach her something and learn to become a better teacher in the process. if she can teach me something, that's also fine.
Ne types are certainly progressive in their worldview. i don't believe you are INTP if you are into nationalism or similar retro crap. anyone with Ne understands progress on their level of development. even an Ne child gets star trek, one world, resource based economy, etc. and would love to see tomorrow to be yesterday. (i don't mean aging of course)
