I bet that this is just lip service, and that the on-the-ground reality will be that, paradoxically, Muslims in Norway will be under more pressure to prove that they are not terrorists. This is how psychological sublimation works : as long as the Norwegians stick to Christianity (and blue eye + blonde hair) as part of their identity, they will be unable to accept that an avowed Christian did what the "other religion" was supposed to be hated for, and the psychological dissonance has to be released elsewhere. This is what religion does to you.
