Well, while Darwin pretty much got the ball rolling, we also don’t call ballistics “Newtonism”, for example. Or relativity “Einsteinism.” Or genetics “Mendelism” or “Watson-and-Crickism.” or what have you. Much of the time the word “Darwinism” really is code so that people can suggest that evolutionary biology is just another “ism”, so that they can suggest that it’s essentially faith based or a religion-of-science. That way they can suggest that it’s just another form of faith (just, ya know, wrong), and not as rigorous as ‘real science’ is.
It’s similar to the “just a theory” gambit.
On another note, while Darwinhttp://boards.straightdope.com/sdmb/newreply.php?do=newreply&p=13696856 got the ball rolling, things have developed significantly since Darwin’s day.
Well, part of the issue is that this is all very important when it comes to governmental/educational policy. The Discover Institute’s Wedge Strategy is an all-out assault on not just our educational system but a rational, ‘materialistic’ worldview as well.
For instance, the original Creationism ‘textbook’, Of Pandas and People, had a great many references to Creationism. But when it was ruled that creationism was of course state endorsement of religion, they simply switched the term to Intelligent Design. This was evidently done by a fairly sloppy global search-and-replace function in a word processing program, which left one interesting term “cdesign proponentsists”, that was discovered during the trial over whether or not “Intelligent Design” could be taught in schools since “Creationism” was right out.
Even now, how the issue is framed is of critical importance. Beaten on both “Creationism” and “Intelligent Design”, they’re hoping to get the tip of the wedge into public policy by framing the debate in terms of “controversy”. There is controversy, they say, over just what evolution is, how it works, etc… and as such, you don’t have to teach “Intelligent Design” anymore, but you must “teach the controversy”. That is, of course, just another backdoor way to get their demands put into the school system, so that teachers have to teach both the actual facts of evolution, and then include a unit on not-evolution. That is, Intelligent Design/Creationism/The Controversy.
