I spent years trying to figure out the Fe/Fi question and a person could make a case in either direction based on the above quote. Fe does seek external harmony, but Fi doesn't necessary love conflict (although some people with Fi engage in a lot of conflict, but that isn't the primary way it is defined.) The following quote is how Jung defines Fe, but I would venture to say it may not actually be a complete representation of it. In his mind it was geared towards women, but since then it has been clear that men use it plenty as well. FWIW, when I read the OP my impression was a bit more INTP than INTJ.
I would have to agree in that it doesn't seem like a complete representation of Fe. Thank you for informing me of your thoughts.
