Simon Baron-Cohen on Breivik's empathy deficit

Simon Baron-Cohen had a piece published in the Guardian today which questions the diagnosis of paranoid schizophrenia on the Norwegian mass murderer Anders Breivik. I posted a response here, with my opinion that the 'diagnosis' is political but also criticising Baron-Cohen for trying to shoe-horn Breivik's crime into his world-view, in which all human actions are explainable through his theories of empathy and systemising. (Any other responses to this, I'd be interested in reading.)
