But the point of my comment (original) was that ID and Creationism are totally separate concepts, though with some commonality. In a venn diagram, I'd give them only about 10% overlap.

Given that one descended from the other and brought a multitude of proponents along the way, this is seriously wrong -- even if one grants all your points for the argument's sake. The one single thing that separates ID from OEC is the explicit deference to the Bible. Every bit of data indicates that this has simply been replaced by an outwardly implicit, but internally explicit deference to it.
