I easily found the page in question, making use of talkorigins.org which has an extensive set of links to anti-evolution sites.

Behe's article was rejected not because of a policy of rejecting anti-evolution articles but because of a policy of rejecting articles which criticised evolution on *non-scientific* grounds
As you no doubt know, our journal has supported and demonstrated a strong evolutionary position from the very beginning, and believes that evolutionary explanations of all structures and phenomena of life are possible and inevitable. Hence a position such as yours, which opposes this view on other than scientific grounds, cannot be appropriate for our pages.
Rejection by a journal is also not unusual - as Behe should know. Many papers are published by journals other than the one they were originally submitted to. And the editors explicitly encouraged Behe to seek publication elsewhere:
Although the editors feel that there has already been extensive response to your position from the academic community, we nevertheless encourage further informed discussion in appropriate forums. Our journal cannot provide that forum, but we trust that other opportunities may become available to you.
If Behe stopped after one submission then that is his choice - and reflects only on him.
