Christian privilege
The concept of hegemony describes the ways in which a dominant group, in this case mainly U.S. Protestant Christians, disseminate their "dominant" social constructions as common sense, normative, or even universal, even though most of the world's inhabitants are not Christian. Christian hegemony also accepts Christianity as part of the natural order, even at times by those who are marginalized, disempowered, or rendered invisible by it. Thus, Christian hegemony helps to maintain the marginality of other religions and beliefs. According to Beaman, "the binary opposition of sameness/difference is reflected in Protestant/minority religion in which mainstream Protestantism is representative of the 'normal'".
The Fall of Hyperion (novel)
The Hegemony is opposed by the Ousters, renegade human colonies that fled the Hegemony's growing influence even before the events of the Hegira. Though seen by many Hegemony citizens as barbarians, the Ousters have a highly advanced culture that focuses primarily on the fine arts and on aesthetic values almost unknown amidst the many technologies of the WorldWeb. The Ousters have mutated physically, believing that they should adapt to their outer-space surroundings rather than adapt the surroundings themselves, as was the case with WorldWeb planets, and appear in a variety of forms throughout the course of the novel. The Ousters have rarely fought full-scale conflicts with the Hegemony, but are launching an invasion of Hyperion at the time of the novel.
