Well that's pretty easy to figure out. You started this thread by posing a religious question. One you aren't prepared to answer concerning evolution. Actually the truth is, the answer to this question is readily supplied by the curriculum in most cases, and is at the entire heart of this controversy. Several states, Kansas and Ohio come to mind, are addressing the problem of athiesm being taught as the official religion of the State in high school classrooms under the guise of "science".
Actually no, I didn't. What I asked was how birth defects reconcile with ID. After posting data and examples at the top of the thread, in my post #1 I added that such tragedies not only argue against "intelligent design," but also are capable of shaking one's faith in religion.
The latter is absolutely true. People the world over and throughout time have had their faith shaken by terrible personal tragedies. It is part of the human condition.
If serious ID proponents are capable of calmly and rationally reconciling -- in the example I used -- birth defects with the theory on a non-religious basis, I am most open to the information.
