The fact that the English equivalent of the Turkish word "halkçılık" (peopleism) is "populism" (and that the Turkish word
"popülizm" can also be used to mean "peopleism") makes it easier to think that all "peopleist" movements are "populist" in the negative sense of the word. However, the Narodniks, for example, who have an important place in the history of the concept of "populism," represented a very different understanding of "peopleism," especially when they first emerged.
Thanks to homeostasis, no matter how much or how little you diet, your body has a strong tendency to hover at that weight. Only by resetting your body's metabolism (say, by exercising regularly) can dieting really help you lose pounds for good. In a marriage, positivity and negativity operate similarly. Once your marriage gets "set" at a high degree of positivity, it will take far more negativity to harm your relationship than if your "set point" were lower. And if your relationship becomes overwhelmingly negative, it will be more difficult to repair.
The riskiest emotions, and thus the most frequently exiled, are acute grief and healthy anger, two feelings that often get tarred as "negative." Of course, a child may also have cause to banish her joy, enthusiasm, or pride if these arouse disapproval, envy, or just blank incomprehension on the part of parents too stressed, distracted, or depressed themselves. Either way, repressing the rejected emotion is the surest way of escaping overwhelming levels of vulnerability, of avoiding a too -painful rift between oneself and the ambient world.
