In the wake of the #Metoo movement, liberal feminism has garnered the spotlight on equal rights for women. However, what factors contribute to men and women developing liberal feminist ideologies? This is important to understand as this ideology is predictive of support for political and social policies that are currently under debate in the United States. In this survey study (149 heterosexual men and 233 heterosexual women) we examined attitudinal and ideological variables that underlie liberal feminist ideology. The results of this study indicate that men scored significantly lower on liberal feminist ideology and significantly higher on traditional attitudes toward women, hostile and benevolent sexism, gender-specific justification, rape myths and conservative political affiliation compared to women. Furthermore, traditional attitudes toward women, hostile and benevolent sexism, gender-specific justification, rape myths, political leanings, and gender accounted for almost 70 percent of the variance in liberal feminist ideology. Participant gender did not moderate the regression analyses, suggesting that men and women are influenced similarly in determining what attitudes predict liberal feminist ideologies. Implications for support for public policy are addressed.
