Even the famous Tennessee "monkey law" of Scopes trial fame didn't outlaw the teaching of evolution. It only forbade public school teachers to teach that men came from animals.
Why all the fuss? If it's really only about science, then it ought to be like the Shapley-Curtis debate. Nobody got all bent out of shape about the "other side" getting a hearing in that case.
Anyway, I have yet to see the movie, so I can't speak to its actual thrust. Soon, though.
ID never offers positive proof . They just attack natural selection. The whole movement is a fraud.
To find out for yourself just what issues were involved in the Scopes trial, visit my FR homepage and download Hunter's Civic Biology, the textbook that caused all the fuss. Then read the darwinism portions.
