The Demands Of Displacement, The Micro-Aggressions Of Multiculturalism: Performing An Idea Of "Indianness" In Singapore, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

This paper explores the ways in which state-defined discourses of multiculturalism can unintentionally create a framework through which micro-aggressions are enacted against those interpreted as "other". These definitions cascade down from the state to majority and then minority ethno-national groups, who leverage positions of relative dominance to establish the terms of acceptance and integration into society. By negotiating these terms, ethnicity becomes a performative construct through which difference is asserted and reified. We illustrate these ideas through an empirical analysis of Singapore's minority Indian community, and how Singaporean Indians perform an idea of "Indianness" in response to their Singaporean Chinese …
