lol, that's why I struggle w/ socionics definitions in the very literal sense that they're often used. if Fi were simply "having morals" and Fe were simply "expressing emotions" they would just be part of the human condition and that makes things too confusing...
Ti types could come up w/ a system of morals that is more explicit using Ti, or they could relinquish their values to the prevailing social milieu w/ Fe suggestive, or they could have a poofed up role function - idk, maybe its more confusing to have so much variation but if I tried to fit ppl into slots that were so neatly defined and created false mutual exclusions, I'd have to just forget it altogether (and I haven't been able to do that, in spite of myself).
