Fe is
bravery when you set your own principles aside and are willing to take the risk of disarming yourself for the sake of maintaining social harmony.
Fi is
courageous if you dare to stand up for your own principles, disregarding from the stance of the general populace. I'm taking
@Deleted member 16771 experience here from when he stood up against the faculty as one of the few defenders on what is right versus maintaining the facade that is the maintenance of the faculty itself. That to me is courageous (one upping you here bud, but it's well deserved).
Fe is
cowardice when it is used as a group principle over someone's well being. I've seen and experience enough examples of people holding themselves in for the sake of some stupid group-setting and withstanding conflict while someone is suffering in silence. It's fucking cowardice when you do not act upon it.
Fi is
egotistical when one's own values are pushed over a group, disregarding the commonality of everyone's principles. It strives for conflict through challenge rather than the necessity to resolve.
The most
courageous on
either is when you dare to take up Fi or Fe as an experience in which you are not comfortable with. These functions are the weakest for either INxJ's. And when I see an INFJ take their best effort to take steps based on inner (Fi) feelings, I have nothing but respect for that.
