No, I don't mock personal feelings, but as @
Pookie so perfectly put it, "We (IEI's) make fun of it and tease the idea of Fi, but it's mostly facetious and our actions reflect a 4d strength in it. If worked on, Demonstrative Fi can be that person who never really does anybody wrong, but nobody notices because we're constantly making filthy, dark-humored jokes and pretending like we don't tip the waitress.
I would say the understanding of personal relationships and connections between people is the part we sort of miss(as it's unconscious in NiFe), but we retain the right or wrong, ethical strengths."
