How does femonationalism, defined as the selective invocation of gender equality to promote exclusionary anti-immigrant policies, affect citizens? While increasingly common across Western democracies, its impact on citizens’ preferences remains underexplored. This paper provides evidence from a preregistered survey experiment with 3,118 U.S. citizens, showing that femonationalist rhetoric can enhance opposition to pluralist policies in defense of progressive gender achievements. The effect is conditional on citizens’ prior immigration attitudes: anti-immigration individuals liberalize their gender views, while pro-immigration individuals demand stricter integration policies. The findings suggest that citizens are not consistent in their ideological preferences, especially when political elites frame liberal values as conflicting.
