Longer Boris Johnson:
Yesterday the television reporters found an acquaintance of his from Norway, a fellow called Ulav Andersson, who said that he had known Breivik pretty well. He was surprised by all the Knights of Templar stuff, because he had never really been religious, and he wasn't aware that he had been interested in politics.
"He didn't seem opinionated at all," he said. He just became chippy and irritable, said Ulav Andersson, when some girl he had a crush on jilted him in favour of a man of Pakistani origin.
It wasn't about immigration, or Eurabia, or the hadith, or the Eurocrats' plot against the people. It wasn't really about ideology or religion. It was all about him, and his feeling of inadequacy in relation to the female sex.
Well, if some guy who said he knew Breivik pretty well said so, who are we to argue? But this theory doesn't explain how Boris covered up all his rejection-based killing sprees.
