The purpose of this study was to assess the frequency and types of negative behaviors directed toward gay men on university campuses and to understand heterosexual men's and women's motivations for engaging in antigay discrimination. Using a mixed methods approach, results from a quantitative survey (N = 286) indicated that students primarily engaged in covert antigay behaviors, such as telling antigay jokes and spreading gossip about gay men. Follow-up qualitative interviews with 8 highly homonegative individuals (4 men, 4 women) were then conducted to better understand their self-perceived motivations for perpetrating antigay discrimination. Results indicated that antigay behaviors were conducted to reinforce traditional male gender roles, alleviate feelings of discomfort, and convey heterosexual identity. Participants also expressed concern about being perceived as prejudiced and were motivated to control their prejudicial reactions to some degree. Implications regarding the contemporary nature of antigay violence on university campuses are discussed.
