In his manifesto Anders Breivik praised Pam Geller. He cited her blog, Atlas Shrugs, and the writings of her friends, allies, and collaborators—Robert Spencer, Jihad Watch, Islam Watch, and Front Page magazine—more than 250 times. And he echoed their tactics, tarring peaceful Muslims with the crimes of violent Muslims. He wrote that all Muslims sought to impose "sharia laws" and that "there are no important theological differences between jihadists and so-called 'peaceful' or 'moderate' Muslims."
He reprinted, as part of the manifesto, a 2006 essay by "Fjordman"—a blogger whose work appears frequently on Geller's site—which argued that "radical Muslims and moderate Muslims are allies" and that because Islam teaches deception, no Muslim who claims to be moderate can be trusted.
Geller's blog and her friends' sites pervaded Breivik's online world.
