This shakes your faith in religion.
I'm not sure it has anything to say about ID other than that, like a car running down with age, natural processes have an impact on design.
Why does it shake your faith?
Why doesn't the designer design his design so that natural processes do not have an impact on the design like a car running down with age?
I'm not sure I understand your question, xzins. I merely said that birth defects, particularly the severe ones, are CAPABLE of shaking one's religious faith. I meant that in a generic sense.
xzins: Why does it shake your faith?
The intelligent design hypothesis has no doctrine, no articles of faith, no Holy writ.
Nor does it specify the "intelligent cause" - which could be either a phenomenon or an agent. Phenomena include intelligence as an emergent property of self-organizing complexity and fractal intelligence. Agents could be God, collective consciousness, aliens, Gaia, etc.
Nor does it address "all features" of the universe and life. Nor is it a theory of origins.
The hypothesis says that "certain features of the universe and life are best explained by intelligent cause rather than an undirected process such as natural selection."
Some people label intelligent design supporters as theists. And some people label supporters of the theory of evolution as atheists.
But neither is a valid because correlation is not causation.
For instance, that a bunch of storks appear at the same time a bunch of babies are born does not establish a cause/effect relationship between the two.
