One thing I've heard is that ENFP's often censor their views to not be contrarian or cause conflict. This is very much unlike my personality. Also, although I do worry about what others think of me, I consider it very wrong to sell myself out in any way or alter my personality to appease them.
This is me. I hate the idea of having to be in conflict with others, but if it's a question of moral high ground, defending another person who needs help, or maintaining my sense of self, then I won't back down, even if it does result in a confrontation.
I never do that.
...people have called me contrarian or conflictual in the past because of that
I've been called something along those lines, along with combative. Which it so unlike me in my normal, relaxed state. Sometimes confrontation is necessary, despite the fact I don't enjoy it, but people seem to think I like doing that sort of thing just because I'm usually in the middle of something. It's a misinterpretation of the situation. I hate conflict, but I can't ignore a situation if something's going wrong.
As far as a dark side is concerned, Pink tells me that I turn into the scariest person she knows when I'm under so much stress I can't handle it anymore. I put on my ISTJ suit apparently, and turn into a flat, affective, steely person. I swear if someone dropped me into a jungle when I'm like that, I could probably liberate an entire village on my own. lol
But it's a very black place, and I hate being there.
