Actually the problem I see with Mac's post is him speaking for other Fe's. That is where the problem lies. I have non-Fi friends who don't feel the same way about Fi.
"Non-Fi see Fi as complaining" is talking for other people and making your point stronger because "other people" feel that way too.
I think this came up earlier in the thread when sleepy(?) protested that Fe can't speak for Fe. However, the very nature of Fe is that it doesn't speak out with certainty until it has gathered enough consensus to be sure it is not alone in the belief being expressed. Fe is also a much less individual function. There are basic guidelines or principles that allow the most work to get done while ruffling the least amount of feathers. We concede that the attitudes reflected then may not encompass each different shade of feeling or individual perspective, but there enough universal agreement and the criteria reached for those guidelines of Fe that most Fe users are going to be fine with it. Fe users may vary in how strongly or weakly they word something or in how willing they are to try to see it from the opposite perspective, but overall, the reactions that Mac has expressed are our first impulses. I have seen very few Fe users ever say "Quit speaking for me! You got it all wrong" when another Fe user says something like this, even though they would be willing to correct misinformation or miscontrued perception of their emotion (so it's not all group conflict avoidance).
While I am committed to trying to understand opposing viewpoints better and to implement that into how I relate to people, I freely admit that my first perception of Fi often is that it is complaining. As such, it sometimes feels as if Fi users are requesting
1) Everyone to adapt to them (even though they are one person and the rest of the group are many who would all have to rearrange themselves to accommodate)
2) They are not subject to the same constrictions we all experience in a group (all of us have issues we feel strongly about - Fe users just tend to try to hold out for the battles most important to them to fight and look for the smoothest way to make their viewpoint understood and accepted. Losing out on the smaller issues is disappointing, but are part of what you lose when you enlist the extra thought processes and ability to harness many people's power for one project or cause)
3) They see themselves as being much more perceptive and unique than other people
4) They want understanding without trying to present the material in such a way that is palatable and taken seriously by their audience
5) They play the victim.
6) They are just unaware and thoughtless.
I do understand that from a Fi perspective, all of these accusations are grossly unfair and inaccurate. I certainly don't feel that reaction to all Fi users, but expressed in an immature form, Fi can grate.
I don't know if that's an emotion or not, PB, but it's what comes to mind when looking at the underlying issues that make us react as we do to Fi.
