Darwinist or Darwinian?

Some tosser over at the so-called Discovery Institute seems to think (I use the word loosely) that I should give a flying fart about whether I’m referred to as a Darwinian or a Darwinist.

For the record, I really don’t mind. You can call me a screaming atheist monkey-man, for all I care. All that matters to me is that it’s perfectly clear to other rational human beings which side of the enlightened/credulous divide it is that I stand on.
