By any definition, the searing tragedy inflicted on Norway and its citizens was the work of terrorism and a sadistic terrorist. Anders Breivik instilled fear through death and destruction in order to effectuate policy change. Much like Timothy McVeigh, however, the word terrorist will slip off Breivik like so much water off a duck's back. Change only Breivik's nation of origin to any Muslim nation (whether secular or not) and he's a terrorist. Why is this important? Terrorists are usually depicted as mindless mass murderers whose only agenda is to destroy anything and anyone who does not share their strict, barbaric, brand of Islam. Their real motives are never investigated by the popular media, it is never suggested that they may suffer from deep mental or emotional instability, and the only people who would sympathize with them are automatically branded terrorists regardless of the fact that they have never harmed a soul in the name of their belief system. I do not mean to endorse any terrorist's actions or motives, but be sure that labels matter. Breivik will be referred to as an extremist (like McVeigh before him) or a "Christian fundamentalist". As an aside, some day someone will have to explain to me what is "fundamental", in Christianity, about death and destruction. These monikers suggests that his views are valid, legitimate, and shared by others who simply have greater control over their impulses; or who share his views, but to a lesser degree of extremity. In other words, being labeled an extremist (or a fundamentalist) means people can share the extremist's views without being labeled extremists themselves; and they can continue to call themselves a "fundamentalist" without the stigma. The only real difference between Breivik, McVeigh, and Omar Saeed Sheikh (remember our beloved Danny Pearl) however, is their nationality.
Additionally, no one should be surprised when pundits (and media outletless babblers) refuse to vilify all white men for Breivik's actions (and I say this as a rather WASPY looking white man), while continuing to vilify all Muslims for Muhammad Atta's actions. Check out this article for a review of the immediate vilification. Both men were monstrous, both meant simply to silence those they dubbed as enemies with murder, and both valued their own messages more than they valued human life.
