From the lens of an educator, I found this book to be useful in understanding my students and some of their behaviors. From the lens of an empowerment self-defense instructor, this book offered some insights into peer socialization of gender norms for both masculinity and femininity and how each is enforced through language in middle school situations. The author suggests that teaching girls to be assertive and to assert their rights may be insufficient and may lead to further ridicule. Instead, their research showed that "making an even more ridiculous or humorous comment , turning the humor back on the initial insulter, or finding ways to transform the meaning of an act or comment into a non-sexual domain" is often more effective (p. 163). The author makes a number of other useful suggestions to help girls (and boys) reject the enforcement and policing of gender roles.
