It seems that most INFJs, including myself, opt not to, despite there sometimes being merit for it. Like for example, if someone offends you, would it be better to call them out on it or protect their feelings? Aren't you neglecting yourself by not letting them know how you feel? And most people probably aren't as sensitive as an INFJ can be, so empathy that we like to call it could be a projection of our own feelings, rather than an understanding of what their feelings would be in that situation. It just seems so unhealthy the way we internalize things, that's why I ask. Hope I'm making sense.
