Breivik 's manifesto '' 2083 : A European Declaration of Independence '' circulated in online fascist forums where strategies were set and tactics debated . In an essay called " Right-wing terrorism as folk activism , " Alt-right philosopher Curtis Yarvin wrote about Breivik , " No one who condones Che , Stalin , Mao , or any other leftist murderer , has any right to ask anyone else to dissociate himself from a rightist who did n't even make triple digits " ( did n't murder more than a hundred people ) . Australia-born terrorist Brenton Harrison Tarrant who killed 51 people ( all Muslims ) and injured 50 more during the Christchurch mosque shootings at Al Noor Mosque and Linwood Islamic Centre in Christchurch , New Zealand mentioned Anders Behring Breivik in his manifesto '' The Great Replacement '' as one of the far-right mass murderers and killers he supports and said " But only really took true inspiration from Knight Justiciar Breivik " even going as far as to claim " brief contact " with him and his organization Knights ' Templar
