Some choice quotes:
At the time, Yiannopoulos, who would later describe himself as a “fellow traveler” of the alt-right, was the tech editor of Breitbart. In summer 2015, after spending a year gathering momentum through GamerGate — the opening salvo of the new culture wars — he convinced Breitbart upper management to give him his own section. And for four months, he helped Bannon wage what the Breitbart boss called in emails to staff “#war.” It was a war, fought story by story, against the perceived forces of liberal activism on every conceivable battleground in American life.
Yiannopoulos forwarded it all, along with the Wikipedia entries for “Alternative Right” and the esoteric far-right Italian philosopher Julius Evola — a major influence on 20th-century Italian fascists and Richard Spencer alike — to Allum Bokhari, his deputy and frequent ghostwriter, whom he had met during GamerGate. “Include a bit of everything,” he instructed Bokhari.
Yiannopoulos managed all of his assistants and ghostwriters under his own umbrella, using “yiannopoulos.net” emails and private Slack rooms. This structure insulated Breitbart’s upper management from the 4chan savants and GamerGate vets working for Yiannopoulos. And it gave Yiannopoulos a staff loyal to him above Breitbart.
