Reveal everyone's personhood.
In many languages in the Fifth World, “person” verbs, rather than nouns. Humans can person, but so can animals, and even plants, rocks, and weather patterns. Stories might person, and even “impersonal forces” like luck or memory might sometimes person. Not everything persons, though. Persons relate to other persons. They can have relationships.
Persons do not embody stereotypes. Instead, they have motivations, histories, and concerns. If someone seems to act more like a stereotype than a real person, show us the parts of their lives where they break those patterns. Show us the reasonable and understandable motivations for even your most hated adversaries and bitter rivals.
