The massacre of more than fifty worshippers at mosques in Christchurch, New Zealand, shocked the world. The murders were not random. They expressed a particular ideology, one that the alleged perpetrator described as ‘fascism’. But what does fascism mean today — and what kind of threat does it pose? Jeff Sparrow traces the history of the far right, showing how fascists have adapted to the new politics of the twenty-first century. Burgeoning in dark places online, contemporary fascism exults in violence and picks its targets strategically. Today, it is Muslims; tomorrow, it will be Jews or gays or Asians. With imitative massacres already occurring around the world, Christchurch must be a wake-up call. This book makes a compelling, urgent case for a new response to an old menace.
