hey, I never knew I was a creationist myself, as I had a paper submitted to Science which got rejected without entering the peer review process...
Not much later one or two articles which were similar in topic made it into Nature. So I could (a) claim that I have been discriminated against for my particular view of my field of expertise, or (b) accept the fact that submissions by people with a proven track record of publishing interesting articles are more likely to be considered.
Science and Nature both have a lot of submissions, if the editors did not select prior to the refereeing process, they would go nowhere (and loose most referees for the sheer workload). So the rejection probably had absolutely nothing to do with him being creationist..
best regards,
Alex
P.S.: The paper shortly after got accepted into another very nice journal, so who cares..
