Is He /ourguy/, a False Flag, or Something Else? Debating Breivik’s and Tarrant’s Terrorism on 4chan’s /pol/ Board

Academic literature widely assumes that extremist-housing online forums, like 4chan, uniformly celebrate acts of right-wing terrorism (e.g. via “sainthood memes”), such as those committed by Anders Breivik and Brenton Tarrant. Aside from a handful of exceptions, this body of research typically fails to acknowledge that ideologically likeminded individuals on 4chan also regularly debate the merits of both terrorists and their violent attacks. Our topic modeling of 100 thousand posts on 4chan’s infamous /pol/ board shows—heated—debates over Breivik and Tarrant ranging from celebratory, to condemning, and moral to conspiratorial. We argue that overlooking these debates limits valuable theoretical and practical insights.
