Antifeminism and the Gender Climate: How Perceptions of Public Opinion Shape Right-Wing Populist Voting | Prior research has demonstrated links between opposition to gender equality and support for right-wing populist (RWP) parties. This relationship is often explained through conservative-traditionalist values among RWP voters. However, little attention has been paid to how individuals’ perceptions of public opinion on gender equality issues shape these dynamics. This study examines the extent to which antifeminist attitudes – understood as a targeted rejection of gender equality achievements and feminist movements – increase the likelihood of voting for an RWP party, focusing on the 'Alternative für Deutschland' (AfD) in Germany. Moving beyond direct attitudinal effects, the study investigates whether extreme perceptions of public opinion on gender equality – that is, viewing society as either overwhelmingly supportive or strongly critical of gender equality – moderate this relationship. It is hypothesized that both types of extreme perceptions can reinforce the link between antifeminist attitudes and RWP voting, as antifeminist views may be either validated through perceived majority opposition or intensified through perceptions of dominant progressive norms. Using representative German survey data from 2025, the study employs regression and moderation analyses to test these assumptions. The findings aim to advance understanding of how perceived opinion climates on gender issues condition political preferences and strengthen support for RWP parties.
