Rush's analogy here is we think terrorists can be domesticated and tamed. They can't. They are in a whole different league here and they are exactly like wild animals. They will kill you without so much as a bye your leave. Ascribing human characteristics to terrorists is just as dangerous as anthromorphizing wild animals. That's the difference between conservatives and liberals. We have an appreciation for danger; they tend to romanticize if not dismiss it outright. Just think of the lib Timothy Treadwell who ended up being bear food. Nature is not Bambi Personified and neither are terrorists.
