There is a scientific approach possible to the problem of creationism. You ask what people mean by the word, both intellectually and emotionally; then you listen the answers carefully and try to translate them into terms both sides can accept. Only then is it possible to disentangle the social and philosophical uses of the term from its status as a quasi-scientific explanation and to promote, so far as possible, the scientific truth.
If Professor Dawkins doesn't know that belief in a creator does not necessarily equate with creationism, then he's an ignoramus. If he does know that, then he's intellectually dishonest. Either way, he is untrustworthy on the subject.
