==Who should care?...It’s the idea that matters, not the sainthood of the messenger.
Well, for starters, if the book is true, we will have to remove Darwin’s name from Darwin Day.
I think I can bear the pain of that action - whatever you decide to rename "Darwin's theory" it won't change his actual writings, or the basic premise.
But if it makes you feel good and you want to presume the book to be true...
Bottom line is that people are trying to make more of BOTH Darwin and ID than is there to be made - neither should invalidate the other whether true or simply reasonable.
