Rape myth acceptance has been extensively studied. Little research is available, however, on the relationship of this variable to other oppressive belief systems. A sample of 492 male and 506 female college students completed the Illinois Rape Myth Acceptance Scale, the Attitudes Toward Women Scale (short form), the Neosexism Scale, the Modern and Old Fashioned Racism Scale, the Modern Homophobia Scale, a modified version of the Economic Belief Scale, the Fraboni Scale of Ageism, and the Marlowe–Crowne Social Desirability Scale (short form). Because there were no existing measures of intolerance toward multiple religions, the Religious Intolerance Scale was developed for this study (using relevant items from the Godfrey Richman Isms Scale). Findings here suggested that greater racism (both modern and old fashioned), sexism (both modern and old fashioned), homophobia (toward both gay men and lesbians), ageism, classism, and religious intolerance were each associated with greater rape myth acceptance. Moreover, each belief system collectively added to the prediction of rape myth acceptance, although sexism has the highest overlap with rape myth acceptance. Although gender did not moderate the relationship between oppressive belief systems and rape myth acceptance, results, across analyses, did indicate that men reported greater rape myth acceptance than women did. Results point to the interrelatedness of rape myth acceptance, racism, sexism, homophobia, classism, ageism, and religious intolerance.
