One is struck by the pictures of the Oslo killer. In some he seems expressionless, but not blank - more as though he felt no need to express himself to others. In other views he provided, we see him absurdly posturing in a range of bogus uniforms and action-man outfits. In the few pictures released of him after the massacre, he looks calm, but oh so smug and satisfied: the cat who really has enjoyed the cream.
His lack of political and social sophistication would suggest more of a diet of Spongebob Squarepants and Powerpuff Girls than serious political philosophy. Personally, I think Marxism has a lot to do with the fact that Marx suffered from chronic severe boils on his bottom, and reputedly had to write most of Das Kapital standing up! Yes, there is over-valuation of Breivik's banal comments. But then the delusion that the world is, and should be, fascinated by all his opinions and actions is widely shared by Tweeters and Facebook addicts.
