This is where you have missed an important element. To the ID proponent, "science" is not what it is to most other scientists, since most ID proponents will assert that ID is science.
		
		
	 
False, and false.
You're not talking about actual ID proponents, but about the moron "creationists" who hijacked things.  Creationists start with a holy book and work backwards and then try to force science to support what they already believe; the ID proponent looks at science, as science, and concludes that there is/was a Designer/Creator.
	
		
	
	
		
		
			ID is merely intuition, (something looks designed, so it probably is). There is no way to test it, or predict things about it, or even to gather quantitative evidence for or against it. So, ID is not science, it is more philosophy or theology. Yet many ID proponents will assert that it is science. The problem is their definition of science will have had to mutate from the accepted one to include such positions.
		
		
	 
Again, you're confusing ID proponents with creationists who hijacked the ID label.  Until the creationists took over, any ID proponent you asked would have conceded quite readily that ID wasn't science, that science could lead you to it, but it couldn't take you to further science.  In fact some elegant proofs were shown that you can't possibly go from P(C) -- the proposition that there is a Creator -- to any sort of science, by the nature of things; roughly, it boils down to one of a few options:
a.  C (the Creator) started things and now doesn't interfere; thus there will be no activity of C to measure in any fashion
b.  C still runs things and keeps them in existence, in which case there would be no way to distinguish activity of C from other activity, because it's all the same thing
c.  either (a) or (b) is true, but C pokes a finger in from time to time, in which case there will be no way to measure any activity of C, because such activity will not be predictable, so you can't set up ahead of time to measure it.
Option (c) fails only if there is a way to monitor everything, all the time, in all possible ways....
I recall a discussion of this once with fellow ID peoploe, and one guy interposed, "But the Bible says...."  We all looked at him, looked at each other, shook our heads, and went back to talking, ignoring him.  When he tried to butt in again, one guy told him quietly but firmly, "This is 
science, and the Bible is not hard data".
