Psychologist Joseph Pleck argues that a hierarchy of masculinity exists largely as a dichotomy of homosexual and heterosexual males: "Our society uses the male heterosexual-homosexual dichotomy as a central symbol for all the rankings of masculinity, for the division on any grounds between males who are "real men" and have power, and males who are not". Michael Kimmel adds that the trope "You're so gay" indicates a lack of masculinity, rather than homosexual orientation. According to Pleck, to avoid male oppression of women, themselves and other men, patriarchal structures, institutions and discourse must be eliminated from Western society.
