On March 15, 28-year-old Brenton Tarrant -- "an ordinary white man," in his own words -- gunned down and killed at least 49 people and wounded at least 20 others at two New Zealand mosques.
World and U.S. media was quick to point out that Tarrant was heavily influenced by far-right and alt-right media personalities, pundits, and quasi-journalists.
"Remember, lads, subscribe to PewDiePie," Tarrant said before opening fire.
"I feel absolutely sickened," the YouTuber said in the aftermath of the event, according to Heavy, which pointed out that PewDiePie has happily platformed individuals like the conservative pundit Ben Shapiro -- a man accused by activist Nathan Bernard of being Islamophobic.
"Arabs like to bomb cr*p and live in open sewage," one of Shapiro's many Islamophobic tweets reads.
Among Tarrant's influences are also President Donald Trump, and commentator Candace Owens, according to The Daily Mail. Following these revelations, Owens took to Twitter to laugh at "racist leftists." She then vowed in another tweet to "lawyer the f*ck up" and sue anyone who dares suggest that Tarrant had been inspired by her far-right views.
But not a lot has been said or written about what is clearly a pillar of Tarrant's vile ideology: Serbian nationalism. As BBC reported, a song which played in Tarrant's vehicle as he was driving to commit the heinous crime was a famous Serbian nationalist song. The song praises the "Butcher of Bosnia," Radovan Karadzic, who was convicted of genocide and war crimes.
Furthermore, names of prominent Serbian nationalists and war criminals were written all over Tarrant's weaponry.
