One of the main reasons I think I'm not INFP and probably not ENFP is that I'm not sensitive. Really. In any respect. I'm physically sensitive, but that's another story. I can't remember the last time I got my feelings hurt, and if it happened I didn't register it. Especially if people try to hurt my feelings- I'll be somewhat displeased that they are mad at me if that's the case, but usually I'll just be thinking "whatever, they're stupid. Obviously that's not true." Or, "I guess I need to let them cool off and then apologize for whatever I did." Or, "well that person sure is bad tempered." And if they are a stranger I don't care. I do care about my reputation and whether I am collectively liked, but it's not something I'm going to cry over- I'll just conclude my social skills suck. I used to be picked on in school, but it never really bothered me. I'd just try to make a joke out of things and see what I could learn from the experience (about how to present myself and interact with people).
I'm not easily offended either. If someone says something that goes against my principles I might feel passionate, but I'm not going to attack their character. When I was a teenager in my morally immature phase I had a more black and white viewpoint and thought all Republicans were evil and fundamentally ignorant, but I quickly evolved past that. The two things I get righteously indignant about are sexism and the environment, and I am more than willing to look at things objectively and not assume an interpretation of what someone says or does.
As for sensitivity to others' feelings: I am aware of people's emotions, but not very good at responding to them and anticipating how they will respond emotionally to things. In fact, I can be pretty terrible at it. I didn't learn how to do it adequately until very recently, and I'm almost 30. Before that I'd just be like, "well that sucks. Let me help you solve the problem. Don't touch me. And go away as soon as possible." I used to offend people all the time and be confused as to why, and then my first inclination was to blame them for being overly sensitive and unreasonable instead of apologize.
So...yeah. Can this be at all compatible with NFP?
