Do ENTP's ever really like people? My boyfriends dad is an ENTP, and I feel like I probably read him better than most... but I sense a very strange, kinda.. dislike for people in general. Kinda like he really thinks everyone is a complete moron that can't be trusted, but he masks it well through witty remarks and charm. I sense that he reserves any authentic, emotional sentiment for those very close to him... pretty much his wife and kid. I don't even sense a real emotional connection to his own parents (my boyfriends grandparents) ... just more of an obligatory relation. Is this possible?
It's not really as personal as "like" and "dislike" really. Thing is, I don't take many things seriously, including most of my relations with people. If that person is a moron, I'll take my relationship with them even less personally (ie. seriously). If they are someone who has won my respect/admiration/found my "mushy" buttons, I'll invest more energy in taking our relationship more seriously. This means I'll invest more precious energy in being emotionally attune to that person. I'll watch what I say around them. I'll try to do little behavioural things FOR that person.
But things like being family don't factor into that, really. Kind of just an arbitrary relationship. If I don't get along with someone in my family I'm supposed to ignore that and love them anyway? See how silly that sounds? What have we done for each other to garner that relationship? Give me some good reasons WHY I should invest emotional energy into our relationship and I will. But most of the time no one does, but we're still expected to be dutiful to our family members. So I do, cause society says so, but yeah you're right, it's more of a duty - an obligation.
How can we get ENTPs to stop thinking for themselves?
Frontal lobotomy?
Ne + Fe loop, how does it look like?
Umm...not sure? Gonna extrapolate from theory and say it looks like neuroticism in the face of social activities. Uncharacteristic self doubt, over-the-top displays of unfelt emotion (in an attempt to manipulate the other person into liking you), seeing what would be the socially acceptable course of action but not knowing how to act accordingly/going deliberately against that to get a rise out of people.
See how easy it is to just make up a bunch of pseudo-intellectual garble?

I dunno...there may be some kernels of truth in it.
How does inferior Si manifest ltself under times of stress?
Kaspar's link it pretty good, actually. Saves time and *sobs* heartache.
