I introduce this chapter with the Macleans article because it aptly illustrates the increasing presence of adolescent girls as public, political figures – one of the arguments I will make throughout this chapter. Yet, I also extend this argument, suggesting that the vocal politics practiced by many teenage girls, including the feminist girl bloggers I discuss throughout this book, must be regarded as a practice of citizenship – a way for girls to participate in the public sphere as political agents. I develop this argument by exploring how feminist girl bloggers produce discursive space within mainstream commercial popular culture to perform feminism publically, a strategy that represents a shift away from the traditional notion of girls’ more passive, private, and apolitical “bedroom culture” (McRobbie and Garber 1991) and raises significant questions about what it means for girls to be public and create public culture within our contemporary neoliberal and postfeminist context. Several questions then guide this inquiry: In what ways are girl feminist bloggers fashioning a new type of girlhood activism through their public engagement with mainstream media? How are hegemonic discourses of girlhood being challenged by such practices? And finally, how might girl feminist bloggers’ public subjectivities demonstrate a practice of citizenship?
