Like the better-known term misogyny, misandry is a pathological aversion for a specific sex group, in this case men. While usually ascribed to women, it is also possible for men to be misandrist. Unlike misogyny, misandry has been little discussed or investigated. Some masculists maintain that misandry has been rampant for thirty years, due to feminist advocacy, and has become a social pathology. Some feminists believe that, while misogyny is a social disease, misandry doesn't exist. Others in both feminist and masculist camps consider the "war of the sexes" arising from traditional gender roles to be a powerful source of both misogyny and misandry.
