Social media has become a key space for young people to experiment with their political voice and to hone it through interaction with others. However, authors Neta Kligler-Vilenchik and Ioana Literat argue that in order to seriously consider social media as a space for youth political expression, we need to put aside conventional expectations about the forms that political expression should take. This empirical and theoretically-based investigation sets the stage for a normative discussion, asking how the forms of expressive citizenship identified throughout the book might bolster-or hinder-democratic engagement. Ultimately, the book considers what it means to take youth political expression on social media seriously, and what the stakes are for political socialization and democratic participation.
