Misogyny (noun): a hatred of women.
Source: Merriam-Webster (online).
Ms. Valenti begins her article What Feminists Can Do for Boys by talking about how feminism ironically “coincided with the rise of extreme misogyny.” Misogyny is mentioned here because feminism resulted in more hatred in women. It is as simple as that and that is precisely why it is an appropriate word she used.
