meh. I suppose all the purity rituals in leftist organization - banning people, demanding adherance to behavior rules, constant search for anyone who doesn't toe the line, are you a real marxist or a mere liberal or progressive, if, among progressives, are you a whack job commie - belies the idea that purity is a conservative thing.
As for narcissistic personality disorder, i guess the class study is Christopher Lasch's? The problem with that one, though, is that in the hands of social commenters at the time, it was a hammer where everyone needed be hit on the head with a "cultural" diagnosis. Everything and anything was labeled narcissistic back then. annoying.
Otherwise, it looks like one of the "spectrum" disorders so vague as to be meaningless. I thought someone exposed NPD as a blanket diagnosis that was used way too much?
Aside: Also, don't forget that, while waiting to eat, people may actually be hungry. With so much of our health problems being connected to a diet high in refined carbohydrates and eating too much at one meal, people increasingly have big blood sugar swings that make them very cranky, irritable, and anxious when they don't eat.
The research on what happens to us when we are hungry is actually interesting. We have a protective mechanism that kicks in to make us hungry and thirsty well before we actually need the food and water. This is a protective mechanism that makes us super anxious to find food and water so as not to ever get in the position of truly being hungry and dehydrated. This was in a book about endurance training, but I can't think of the title/author right now.
With increasing levels of glucose intolerance in the population, these mechanisms kick in with a vengeance to make people super hungry in response to swings in blood glucose.
