Typical ID response to rebuttals?

If the ID proponents are going to ask for experimental support and then suggest that it is invalid because it is a "non-natural" experiment they will look more than a bit disengenuous.The point is: a claim was made that such systems (IC) can not evolve throught mutation and selection. It doesn't matter in this context, based on the logic behind the suggestion about IC systems, where the selective pressure comes from . If through evolutionary processes (mutation and selection) an IC system can arise the basic concept of IC as a refutation of evolutionary theory is blown out of the water.If you are actually suggesting that the IC concept as an attack on evolutionary theory is in any way affected by the source of the selection I would love to see your logic for that.
