First of all, I've been in a lot of physical pain this week - if my tone is or was curmudgeonly, it's more about that than anything else.
That being said, I didn't really want to go on a point-by-point analysis of everything I disagreed with (about the first bunch of posts) because it's actually already been said in past discussions in this forum, ad nauseum. It's not just my experience that doesn't jive with the usual Fe conceptions - this discussion has happened many times, and I've lost all motivation to keep articulating why aspects of it don't make sense. But I do feel compelled to at least state, for the record, where some Fe/Fi distinctions are posted that run contrary to my experience. (Because if no opposition is stated at all, then incorrect distinctions can congeal and become 'common knowledge').
It may also have to do with the fact that INFJs are introverted intuitive doms and not feeling doms?
Yeah, if the discussion is going to be about INFJ 4s and INFPs 4
specifically, then it makes far more sense to compare Fi with Ni, instead of Fe.
Both Fi and Ni doms typically feel an urgency to stay authentic/true to self, but I think the criteria for authenticity is a bit different for each. There is a "right now" immediacy for Fi that Ni tends not to prioritize, while Ni(Fe) tends to need a certain amount of consistency to consider anything truly authentic. Both tend to (at least, if past conflict in this forum is any indication) find the other's criteria unsatisfying and constraining.
But other than that, I do think INF 4s are more alike than not.
