It is remarkable how few Westerners know that Indonesia is the fourth most populous nation (after China, India, and the United States), or that Indonesia is home to more Muslims than any other country. These basic facts should be enough to establish Indonesia’s importance for current world affairs. In this essay, however, I argue for paying attention to the life-worlds of gay and lesbian Indonesians. While this might seem an unconventional topic, these Indonesians’ lives provide valuable clues to how being ‘Indonesian’ gets defined and to the workings of nation-states more generally. They teach us how heteronormativity—the assumption that heterosexuality is the only normal or proper sexuality—plays a fundamental role in forming nation-states as “imagined communities.” In Indonesia and elsewhere, nation-states are modeled on a particular archetype of the nuclear family (husband, wife, and children, with the nation’s president as parent). In line with this model, nation-states often portray themselves as made up not just of individual citizens but of families, which almost always are assumed to be nuclear families despite the staggering range of family forms found in the world’s cultures. Restricting the family model to the heterosexual couple has been a key means by which the idea of the Indonesian nation (and other nations) has been promulgated and sustained. Thus, rather than see the exclusion of homosexuality as a latter-day response to an encroaching global gay and lesbian movement, this exclusion is most accurately understood as a point of departure by which the idea of ‘Indonesia’ comes to exist in the first place.
