Book excerpt: -- The editors of this volume are mid- to senior-level scholars who each have significant publications on digital hate and extreme speech. The collection arises out of a conference which received EU funding to study the rise and spread of extreme speech in the digital age. -- Any good work on digital extreme speech would be useful in an era of right-wing nationalism, rampant racism, and online calls for violence. What makes this collection particularly significant, though, is its focus on expanding the conversation to encompass a more global outlook. In doing so, it encourages readers to have a fuller and more nuanced understanding of the ways in which the Internet operates across the world. -- Methodologically and theoretically, it combines the lens of media anthropology and communication studies. This makes it a unique contribution to anthropology and communication studies, advancing as well growing scholarly interests in digital politics and online communication among sociologists, political scientists, international studies and development studies experts. -- The audience for the work is upper level undergraduates, graduate students, and scholars working in global communications, new media studies, international studies, anthropology and sociology as it relates to media and the Internet, and political science. The work would also appeal to media activists, NGOs engaged in hate speech interventions and peacebuilding, and governmental and media organizations.
