The rallying cry of "Free speech!" has long served as a touchstone for liberals and conservatives, alike, engaged in political polarization conflict and discourse. The democratization of media and the feverish pitch of political polarization, however, have contributed to the weaponization of free expression. From Colin Kaepernick to "fake news," boycotts of partisan television programming to removals of Confederate monuments, internet neutrality to the silencing of college professors and all points between, citizens and pundits all too frequently wield the slogan of "Free speech!" as the sword and shield of political discourse. Oftentimes, ironically they do so with little regard for the views of their opponents. As a result, society risks trading a substantive value for an empty slogan or, far worse, blind authority.To rediscover the underlying assumptions and social values served by free expression, and to move current controversies beyond rhetorical flourishes, Helen J. Knowles and Brandon T. Metroka assemble an impressive group of legal and political scholars to address one overarching question: "Why should we value free speech?" Through analyses of several recent controversies invoking concerns for free expression, the contributors to this volume make complex political theory accessible, informative, and entertaining. Beginning with internet neutrality and ending with an overview of developing free expression controversies in comparable western democracies, experts reestablish the link between free expression and the underlying values it may serve. In doing so, this volume unearths values previously unexamined in our modern—but increasingly impoverished and bitter—political discourse.
