Creationism as a lost opportunity
It is hard to argue with the negative context of creationism given that it has become a tool of the religious right and is just anti-Darwin and anti-science.
Too bad, because it could be an ecumentical tool. In the correct context it might mean that a supreme being could use evolution and scienticfic method as tools to acomplish his work.
This would not satisfy the atheist but it would sit well with most Agnostics.
