From international press coverage of the French government’s attempt to prevent Muslims from wearing headscarves to terrorist attacks in Madrid and the United States, questions of cultural identity and pluralism are at the center of the world’s most urgent events and debates. Presenting an unprecedented wealth of empirical research garnered during ten years of a cross-cultural project, this book addresses these fundamental issues by comparing collective actions by migrants, xenophobes, and antiracists in Germany, Britain, France, the Netherlands, and Switzerland.
