From the New York Times:

The man accused of the killing spree in Norway was deeply influenced by a small group of American bloggers and writers who have warned for years about the threat from Islam, lacing his 1,500-page manifesto with quotations from them, as well as copying multiple passages from the tract of the Unabomber.

In the document he posted online, Anders Behring Breivik, who is accused of bombing government buildings and killing scores of young people at a Labor Party camp, showed that he had closely followed the acrimonious American debate over Islam.

His manifesto, which denounced Norwegian politicians as failing to defend the country from Islamic influence, quoted Robert Spencer, who operates the Jihad Watch Web site, 64 times, and cited other Western writers who shared his view that Muslim immigrants pose a grave danger to Western culture.

[…]

The revelations about Mr. Breivik’s American influences exploded on the blogs over the weekend, putting Mr. Spencer and other self-described “counterjihad” activists on the defensive, as their critics suggested that their portrayal of Islam as a threat to the West indirectly fostered the crimes in Norway.

Mr. Spencer wrote on his Web site, jihadwatch.org, that “the blame game” had begun, “as if killing a lot of children aids the defense against the global jihad and Islamic supremacism, or has anything remotely to do with anything we have ever advocated.” He did not mention Mr. Breivik’s voluminous quotations from his writings.

It sounds to me like Mr. Spencer is saying that all the stuff he wrote on his blog about the evils of Islam were really of no consequence and weren’t meant to influence anybody. Which makes me wonder why he bothered to write them in the first place.
