Many years ago, Ted Bundy was executed. While I'm not particularly a fan of capital punishment, some executions disturb me less than others, and Bundy's was one of those. I believe that most Americans would generally agree with me on that point.
It would have been utterly disturbing to imagine someone going into Bundy's cell to ask him what he wanted, and how we could have accomodated his wishes. Bundy deserved no such consideration, and the mere suggestion that he did would have evoked a LOT of outrage across the country.
Yet the current vein of PC thought has us geared to do exactly that with terrorists. While some bloggers on the site have pointed out that if we don't have the stomach to slaughter the Islamic extremists outright, we have to face the fact that we must negoitiate with them. But that negotiation should not include acquiescence to their outrageous demands.
There are far too many who think that an Islamic terrorist who straps bombs to themselves is somehow the same as a Christian who preaches on the street. That assertion is not only utterly ludicrous, it is sad indeed. While it is true that some extremists who call themselves Christians could, with the right catalyst, be driven to such actions, the fact that such examples are not really widespread in the 2000 year history of the faith should indicate that it's not a key tenet. And, while I realize the claims of those who would say that Mohammed himself advocated the same level of terrorism are widely debated, it is reasonable to say you can find more support for the terrorist mentality in the teachings of Mohammed than you can in the teachings of Christ.
Whether Christian, Muslim, atheist, what have you, murderers are murderers, and it is not our duty to "understand" them, or to try to "heal" them. They've proven their unfitness to be an active part of our society, and, while we don't necessarily need to execute them, we certainly don't need to try to "understand" them.
