摘要:Drawing on the literatures on dual identity and politicization, this study relates the political engagement of European-born Muslims to their dual identification as ethno-religious minorities and as citizens. Minorities’ political engagement may target mainstream society and/or ethno-religious communities. Surveying the Turkish and Moroccan Belgian second generation, our study analyzes their support for religious political assertion, participation in ethno-religious and mainstream organizations, and trust in civic institutions. Its explanatory focus is on the dual ethno-religious and civic identifications of the second generation and on perceived discrimination and perceived incompatibility as threats to their dual identity. Our findings show that participation in organizations beyond the ethno-religious community is most likely among high civic and low ethnic identifiers, and lower among dual identifiers. Rather than increasing political apathy, perceived discrimination goes along with higher levels of participation in both ethno-religious and mainstream organizations. Finally, the perception of Islamic and Western ways of life as incompatible predicts greater support for religious political assertion and lower trust in civic institutions. Implications for the role of dual identity and identity threat in the political integration of ethno-religious minorities are discussed.
