So,what?
Why does Krauthammer,and others, believe that it's their mission in life to parade the truth of scientific orthodoxy upon the school systems?
If intelligent design is false it will fall out of favor, and be discredited on the facts. The world will still spin, and birds will still fly.
The larger question is: Who decides what is taught in schools - liberal bureaucrats, the MSM, or parents?
We've already seen one judge rule that parents have no control over what is taught in schools. Whatever one thinks of the ID/Evolution controversy it should be remembered that parents are under fire to cede control of their children to liberal educators. That's more important than any theory, and Krauthammer should recognize that.
But a whole generation or more of children will have grown up scientifically ignorant because they wont understand what science is or how it works.
What you say is equivalent to lets accept Islam as our faith and if it is wrong it will fall out of favor and the world will stil spin and the birds will still fly.
ID has been around in its present form for over 200 years without doing any research or contributing anything to the understanding of biology. The only honest thing it has done is retreat in the face of accumulating facts.
It has now retreated to the point where its main advocates -- Behe and Denton -- accept evolution and common descent, just as mainstream biologists do.
But you knew that already, right?
