A reformed conspiracy theorist is giving an insider’s look into the world he once sat at the center of, and it’s not a pretty one.

Charlie Veitch says that the modern conspiracy narrative involves the deeply embedded belief that the few control the many, and that the “few” are the Jews. Speaking to The Telegraph, Vietch says that anti-Semitism was par for the course, and he was often the target.

“Loads. Loads. I was once accused of being a Jew because of my olive skin and my nose. They said, ‘We can’t trust him’.” When they say the ‘Illuminati’ or ‘Reptiles,’ do they actually mean Jews? the Telegraph reporter asks him. “It’s slightly complicated but, mostly, yes,” he says.

Veitch gained a following as a vocal proponent of the belief that the 9/11 terror attack was an inside job, a controlled demolition carried out by the U.S. government. His online videos sparked the interest of high profile conspiracy theorists such as American radio host Alex Jones.

But the turning point came when Veitch took part in a BBC documentary, Conspiracy Road Trip, made to mark the 10th anniversary of 9/11.

During the filming Veitch met experts including the chief air traffic controller on duty during the 9/11 attacks, demolition specialists and architects. At the start, Veitch was defiant, but as production continued he began to change his mind.

“This is hard, you know, because I’ve hung on to these ideas for years now,” he told the film’s presenter, Andrew Maxwell. “I’ve always hung out with people who say, ‘Yeah, conspiracy! 9/11 demolition!’ But now I’ve spoken to a guy who’s explained it. And it makes sense.”

Veitch now has few kind words for the world he once inhabited. He describes it as a world full of “evil-worshipping paranoia. As someone who’s been deep in it, and seen the hatred and the insanity, I think big terrorist attacks will come from conspiracy theorists.”

“Conspiracy theorists,” he says, are often “bullied people. People who maybe didn’t get the girls at school… So they see a lot of rugger bugger types and they’re against anything to do with them. They will side with the devil, as long as the devil is against the West.”
