“…A possible explanation for these gender differences is the theory that anti-gay attitudes are embedded in gender belief systems (Kite & Whitley, 1996): Sets of beliefs about men and women, about masculinity and femininity, including gender-role attitudes and norms, gender stereotypes, and perceptions of individuals transgressing such gender roles (for a recent review, see Herek & McLemore, 2013). Indeed, traditional gender beliefs are correlated with anti-gay attitudes (Basow & Johnson, 2000;Brown & Henriquez, 2008;Costa & Davies, 2012;Goodman & Moradi, 2008;Parrott et al, 2011;Swank & Raiz, 2010;Vincent et al, 2011; for a meta-analysis, see Whitley, 2001). Gender beliefs can explain why heterosexual men have more negative attitudes toward (male) homosexuality: Heterosexual men often hold more traditional gender beliefs than heterosexual women, and this has been found to mediate gender differences in attitudes toward homosexuality (Kite & Whitley, 1996).…”
