As an INTP, I still struggle to completely grok the merits of Fi. I do believe that theoretically healthy Fi creates true empathy rather than the forced harmony I've witnessed with Fe-types, but I have to confess that I am extremely biased as most of my Dominant Fi friends in life have not been there for me when I really needed them. My relationships with them always came back to them. I would get frustrated and think "do I really have to fucking show emotion to prove that I'm human and worthy of love?" I would say that I gave up on those relationships, but I am fairly certain that they gave up on them first.
I'm extremely jaded because of my past. I have not discounted the possibility that I will one day form a close bond with a strong-Fi type that will be equitable, however.
