Theland,
Very nice question, I enjoyed reading the article. Some of the answers here have left me a little confused. Some people seem to be criticising this argument for things it is not really saying. The author is not arguing creationism vs darwinism, more that the debate should take place. His basic point is that darwinism, like creationism, is a theory. He offers some arguments against darwinism (some are better than others, i'll look at them later) but really he is saying that science is about criticising theories and producing improvements, how can you do this if only one theory is ever looked at.
Jake-the-peg has produced a sound argument vs creationism, but to say it is bad science seems redundant. It is after all, not really a science. Also the science that is looked at in the article is not creationism, The article is for the most part concerned with darwinism.
A number of anti darwinism arguments are put forward. Some are based on science, some are more social. The social ones, for the most part, are fairly weak in my opinion. Gef says the article blames darwinism for racism. This is not the case. The article says that darwinism could be used as an argument to fuel racist beliefs. This is in fact the case, e.g. "Evolution has caused us to be superior." However this is not a good anti-darwinism argument, since lets face it, religion tends to do similar things.
