Intelligent Design and Lung Cancer, An analogy

A while back I was lamenting the Intelligent Design attack on teaching evolution  to a good friend of mine who happens to be a teacher.  Imagine my dismay when she said, "Well, I just believe in putting all the theories out there, and letting the kids make up their own minds."  She is an old and dear friend, so I bit back the snarky retorts like, "Do you teach them the flat earth theory, too?" - which left me with little to say.  The conversation has stayed with me, however, because it has become obvious that there are a lot of people out there like her - intelligent,religious people who aren't that scientifically literate - who have bought the argument that Intelligent Design and Evolution are both theories and therefore equivilant. Clearly, the current efforts to explain the difference are not working. More...

So, I have come up with this analogy which, if delivered in a polite, non confrontational way might get through to those non fanatics who have fallen for the pseudo reasonableness of the ID folks:

1. It is a scientific theory that smoking causes lung cancer.

2. Everyone who smokes does not get lung cancer, and people who don't smoke do get lung cancer.  Obviously, there are gaps in the theory.

3.  There is a religious belief that everything is part of God's Perfect Plan.  This would explain why some smokers don't get lung cancer and some non-smokers do.

4.  Do you really want both the scientific theory and the religious belief taught side-by-side in our children's health class so they can make up their own minds?

Whaddya think Kossacks?
