given an inch, they take a light year.
From my point of view, science attempts to answer the provable, testable HOW of things and belongs in science class. Religions of all stripes (including so-called creationism repackaged as "intelligent design") arrogantly claims to address the unprovable and untestable WHY and belongs far away from science class - philosophy maybe, if one is feeling generous. The two might be able to coexist, but not in a SCIENCE classroom.
Of course, the Catholics rejecting I.D. will simply inflame the Catholic hating hard of thinking I.D. crowd even more, so there's no net gain there I think. People such as tfagan, who wouldn't understand the concepts and interplay of "testable", "proof", "hypothesis" and "theory" if it hit them in the head with a large iguana. Or even a finch beak.
