I checked: on the MBTI model, all official Fi-users (the MBTI FPs and TJs) have Te in the top four. So I suspect/hypothesize/wildly guess this:
when an Fi user starts talking about feelings, it comes out Te-flavoured.
(And someone else'll have to disprove that because everything I'll ever say will come out Te-flavoured and I wouldn't know.)
that might be the origin of Fi-users claims that Fe-users manipulate. Because Fe doesn't hear Te.
It goes something like: an Fi-user makes some feeling claim, possibly some claim of ownership and a requirement of respect, and Fe keeps on keeping on because it hasn't heard anything that feels like feeling, so Fi is all, like, WTF?! Aren't you listening? And Fe says, I'm listening, I respect your feelings, I'm *smile*, so let's [insert some Fe requirement here].
Or am I just picking on the cripples again?
