According to multiple news reports in Norway and Sweden, Brievik belonged to Oslo's extreme right wing. He was a frequent poster in Norwegian right-wing online forums, the accounts said, and had two guns registered to his name. He also appears to have launched a social media presence just days before the attacks.
In Breivik's Facebook account, now removed, the suspect identifies himself as a Christian conservative. However, that was far from his only interest. Breivik also listed himself as a fan of World of Warcraft, Modern Warfare 2, bodybuilding and stock analysis. The account, which appeared to have only been started last week, was mostly filled with music videos. Breivik, who listed himself as single, said he had completed "3,000 hours of study in micro and macro finance, religion."
Breivik appears to have started a Twitter account on the same day as he launched his Facebook presence, July 17. The account, which has not been removed, has just one tweet to its name. It's a quote from the philosopher John Stuart Mill: "One person with a belief is equal to the force of 100 000 who have only interests."
