Actually, that's not the way I view it. The only people who I ever see using the term "Darwinist" are those attacking the theory of evolution.
I did a number of courses in human evolution, problems in human evolution, human osteology, and human races, and spent half of my Ph.D. exams on those subjects, and in six years of graduate school, not once do I recall the term "Darwinist" being used.
Here on FR, it is an everyday occurrence from one half of our spectrum.
But its better than what I usually see in these threads!
If I had to guess the reason, I'd say it's because it wasn't being seriously compared to anything else, such as Lamarckism or Lysenkoism, let alone some form of intelligently guided evolution. In other words, the premise was considered a given, so it wasn't a subject of debate. Here on FR, the premise is a subject of debate.
