Far-right terrorist ‘manifestos’, like the one apparently published by one of the Christchurch shooters, are a kind of Rorschach test, inviting the reader to finish the job by finding meaning in the incoherent and contradictory ideas it contains. An act of mass murder is turned into a global spectacle by the use of real-time social media networks. Traditional media organisations and individuals online are drawn into repeating, arguing over and sharing the claims and images made by the perpetrator.
