So the attorney's argument is that it's not fair to ID proponents that science only studies the natural universe. And we're supposed to take this seriously?
What about teaching ID as "the controversy"? This is a sham for introducing ID as being on an equal basis. ID says there is a controversy about evolution--a controversy they have contrived that is peculiarly focused on biology. Let's extend this to all "controversies" we can imagine:
I do not believe in the Pythagorean Theorem--there are gaps in the proof, I do not accept your proof, and I think triangles can have more than 180 degrees. Obviously God designed triangles, and my belief in God trumps geometry. This "controversy" will help all students who fail their geometry tests!
I do not believe in gravity. We accept that gravity makes apples on earth fall, but it is angels that push the planets around. Saying otherwise is merely circular reasoning. Teach the controversy.
Why are students required to believe in atoms and molecules? There is not a single mention of them in the Bible, nor in the Declaration of Independence. Electrons and atomic forces promote atheism and moral relativism in the public schools. Teach the controversy.
I've never been confident about airplanes staying up. Some say that it is due to secular engineering. NASA and Boeing engineers are of the elite. Who would believe them? I suspect fairies. Teach the controversy.
