But it's certainly our privilege under the Constitution to grant a say to cheerleaders on a sinking ship. In short, evolutionism is but an aberration in the general practice of pure science, easily overcome by common sense. Why it usurps the name "science" for itself is something of a mystery. Maybe ego has something to do with it.

There you go again, trying to redefine science in order to get religion classified as science.
