YES OMG some people HAVE TO BE CONFRONTED and all the Fe nudging in the world isn't going to work on them!!! Not everybody, just certain individuals. I agree, I totally agree.Thus to effectively teach them a god damned thing, you have to be REAL. Any sense that you are not REAL, or are planning and plotting...and they assume Te and respond assertively, defensivly, and even aggressively.
Thus to truly impact their judgment on an issue, you must be REAL. Whatever issue it is you feel strongly on....it has to REAL...and it has to force them to hurt just a little via their own internal Fi mirror, small though it may be.
You effectively teach them how to not hurt others with Te, by showing them how they have hurt you. They dont typically mean to hurt others...they just seek effeciency which can sometimes hurt others.
Thus this exceptionally strong desire for Fi to be highly authentic may derive from an evolutionary perogative for Fi-Te social interactions to rest upon Te being used as the controlling factor, while Fi is an effective tool for empathic communications.
