hostilarchy (n) - a system of rule by people whose unreflected, reactionary, anxiety-based aggression has been normalized, especially through existing and pervasive ageism, sexism, racism, ableism, classism, colonialism and other forms of oppression (Latin 'hostilia' = 'aggression' + Greek 'arkhia' = leadership, rule, government)

Hostilarchy can be mapped within other social hierarchies, such that 'hostilarchs' ignore or neglect their own e.g. gerontarchical, patriarchal, white-supremacist, ableist, etc. behaviour(s).
