part of what is being described is how entp/estp experience Fi.
I've thought of that... that what you guys have been describing as "social rules" or "social etiquette" is just how Fi looks through Fi PoLR eyes.
For example, if a guy is talking to me and he doesn't respect a boundary while trying to fill his Fe hidden agenda (this just happened less than a week ago), my response would probably seem cold to him. In another situation (or if he didn't drop it) I may have expressed to him in one form or another that his behavior is inappropriate.
Now, my response to him had
NOTHING to do with "social rules" or "social etiquette", but I could see from his perspective how he might think it does. (Interestingly, now that I think about it, he may even think I dislike him, which isn't the case.)
We see the world through colored glasses, and the color is our quadra values. If I was looking through blue glasses and I saw something yellow, to me it would look green, and if I didn't know any better, I'd probably call it that. ExTps see people's responses to their Fi violations through Fe/Ti glasses. It's no wonder that what they perceive is "social" "rules" or "etiquette".
