INFJs often try to make INFPs seem like they're lazy & unmotivated & only react in a pouty, bratty manner when they don't get their way; in a word, they see the INFP as childish, and that's how this description reads to me. I don't think Fi is all nicey-nice, but it's significantly deeper than Fe, and here it's made to sound rather immature & shallow even. As it says in Psychological Types concerning Fi: "because it usually does nothing visible, and an extraverted consciousness is unable to believe in invisible forces." Fi is a lot more conceptual or "invisible"; it's more about creating internal models of the ideal than seeking to affect people, and so there is more time spent in reflection than action concerning Feeling. However, this means action on the part of the Fi-dom can be more profound in meaning.
Since I am looking at the other functions from the outside, that may be why they seem more acceptable to me though.
If I was not familiar with MBTI & other function descriptions, I don't know if I'd be typing myself Fi-dom from this.
