Excerpt:
Anders Behring Breivik was a prolific blogger and visitor to online sites that reaffirmed his worldview.
Breivik's taste in online conversation shows a compulsive interest in websites that see the modern world in terms of a "clash of civilizations," where Christian values are supposedly under siege in the face of an Islamic onslaught.
But rarely if ever does he seem to have advocated a violent response to what he saw as the Islamization of Europe, even as he planned a massacre for years.
The head of Norway's intelligence police, Janne Kristiansen, told a Norwegian newspaper Monday that Breivik had "deliberately desisted from violent exhortations on the net. He has more or less been a moderate, and has neither been part of any extremist network."
