Anti-Muslim policy preferences and boundaries of American identity across partisanship

Does American identity predict preferences for anti-democratic policies that aim to marginalize Muslim Americans? Absent significant priming of inclusive elements of American identity, we argue that individuals with stronger attachments to American identity will be less likely than their counterparts to reject a range of anti-Muslim policies that are antithetical to principles of religious liberty and equality. Across three surveys and multiple measures, American identity powerfully predicts preferences for curbing the civil liberties of Muslim citizens. Particularly striking is the finding that the effect of American identity spans the partisan divide; it consistently explains the endorsement of exclusionary policies among self-identified Democrats, who typically hold more progressive policy positions toward minority groups than Republicans. Overall, our study highlights the contradictory and exclusionary nature of American identity, which has important implications for minority groups constructed as outside the boundaries of Americanness.
