Thanks for the elucidation, Luce. It just irks me that almost the only time the term shows up it's used in the sense of 'someone who worships Darwin, or follows Darwin as an authority figure'. I have heard the term used by evolution proponents and it's always seemed to me to be in reaction to vociferous opponents using the term in a perjorative sense. I am unaware of anyone who "believes" in Darwin, or Darwinian evolution, in the same manner that you "believe" in Yahweh; i.e. there aren't many evolution churches, perhaps with huge marble statues of Charles Darwin, around.
