Exit 'science of religion'?

In an initiative called Just Science 2008, bloggers are encouraged to participate in 'a week of science':

"By signing up you stipulate that you will post at minimum 1 scientific post per day between February 4th and 8th of 2008. Additionally, you may not post any non-science entries for this period so that we may offer only science on our aggregated feed. What counts as science and non-science? [...] A post which uses a reference to Creationism before elucidating a biological topic is science; a post which discusses the social and religious dynamics of Creationism is not."

Does this mean that ‘science of religion’ in general is not science?
