Probably because many of the big guys in the ID movement have let slip at one time or another that their real aim is to get religion back into biology.
It's too bad they let that 'Wedge Document' get out.
Governing Goals
* To defeat scientific materialism and its destructive moral, cultural and political legacies.
* To replace materialistic explanations with the theistic understanding that nature and human beings are created by God.
If you really, truly believe ID is anything other than a camel's nose poking into the tent, you're being played for a sucker.
I think the Wedge Document deserves its own thread.
