Post-industrial societies increasingly face conflicting forces that simultaneously advance and resist gender equality. While policy efforts have advanced women’s and sexual minorities’ rights, a reactionary discourse has gained traction in Europe, often framed as a “war on gender ideology”. As conservative and far-right actors strategically politicize these issues, societal attitudes become a critical battleground of competing ideological narratives. While research has extensively explored the role of sexism in shaping voting behavior, comparatively less attention has been paid to the influence of attitudes toward sexual minorities. Notably, it remains unclear how social groups combine support for women and sexual minority rights and how polarized these attitudes are, reflecting a potential attitudinal divide. To addresses this gap, this study poses two key questions: (1) To what extent do attitudes toward women and sexual minority rights differ in their degree of polarization? (2) How do these attitudes shape voting behavior, and are there discernible differences in their influence? Using original survey data collected in ten European countries, this paper explores the similarities and differences in attitudes towards women and sexual minorities and links both to voting behavior. As such, this study enhances the literature theoretically and empirically by establishing a link between attitudes on the two issues, and by providing a deeper understanding of how divides over gender and sexuality intersect with political preferences, shedding light on the factors shaping electoral behavior in contemporary democracies.
