Excerpt: All of this would be an interesting though not terribly important semantic matter if not for the fact that the term Terrorist plays a central role in our political debates. It is the all-justifying term for anything the U.S. Government does. Invasions, torture, due-process-free detentions, military commissions, drone attacks, warrantless surveillance, obsessive secrecy, and even assassinations of American citizens are all justified by the claim that it's only being done to "Terrorists," who, by definition, have no rights. Even worse, one becomes a "Terrorist" not through any judicial adjudication or other formal process, but solely by virtue of the untested, unchecked say-so of the Executive Branch. The President decrees someone to be a Terrorist and that's the end of that: uncritical followers of both political parties immediately justify anything done to the person on the ground that he's a Terrorist (by which they actually mean: he's been accused of being one, though that distinction -- between presidential accusations and proof -- is not one they recognize).
If we're really going to vest virtually unlimited power in the Government to do anything it wants to people they call "Terrorists," we ought at least to have a common understanding of what the term means. But there is none. It's just become a malleable, all-justifying term to allow the U.S. Government carte blanche to do whatever it wants to Muslims it does not like or who do not like it (i.e., The Terrorists). It's really more of a hypnotic mantra than an actual word: its mere utterance causes the nation blindly to cheer on whatever is done against the Muslims who are so labeled.
