He called himself the Gypsy Crusader. For his live video streams, he dressed up as the Joker, the Riddler and Super Mario. He sat himself in front of a Nazi flag and launched tirades of hate in all directions as he recruited new believers for the inevitable day of racial reckoning. For effect, he would wave weapons around. His real name was Paul Nicholas Miller, 32, a once-promising kickboxer from New Brunswick, who by late last year had been banned from all mainstream social media platforms. Still he grew a sizeable following in the darkest corners of “alt-right web” communities. The more racist, antisemitic and violent his message, the more popular he became. Paul Miller provides one of countless modern-day American stories that illustrate how readily a young man’s disillusionment can rather easily be transformed into unbridled radicalism in today’s social climate. And Miller’s story shows how fragile that construct can be and how unceremoniously it can collapse.
