The traditional image of Halflings among the other races, when they think about them at all, are of an inoffensive people, cheery, optimistic, lucky, brave, and curious. All admirable qualities, even if it does give a somewhat patronizing account of the race.
Of course, Halflings are more diverse and complicated than that. But another attribute of the Halfling race is their ability to fit in, to get along, with Humans, Elves, Dwarves, and (occasionally) Orcs they live with. They assimilate. They pass. They put a lot of effort into being seen as inoffensive.
This is because for the most part, Halflings are a people without a homeland. Halflings tend to live in the lands of Humans (or Elves, or Dwarves, etc.), and not the other way around. So they adapt, and adopt. They adopt the mannerisms, the language, the religions, and the loyalties of the races they live with.
Part of the adoption mean accommodating the societal mores in which they live. Sometimes, of course, the society is intolerable, in which case the Halflings simply move on to greener pastures.
But sometimes, a Halfling can’t just move on. They reach the end of the line, either literally or psychologically. If a Halfling makes the decision that they simply can adapt themselves to the society anymore, and they can’t move on, that leaves only one option- adapting the society to suit themselves. Sometimes, that leads to Anarchy.
Halfling Anarchists tend towards the Pacifist, Individualist, Collectivist, Mutualist, Environmentalist, Equalizer, Free Marketeer, Insurrectionist, Illegalist, Platformist, Poetic, and Philosophical traits.
