The ACLU will easily win.  First Amendment case law is perfectly clear that government cannot be in the position of favoring one religious group or doctrine over another.  There is, admittedly, sometimes a legitimate question what, exactly, qualifies as a "religion."  It's not clear to me, for example, why the fantasies of Scientology aren't a religion while the fantasies of Prevo are.  But taking that approach is an obvious loser for KPB, since it could be challenged by an infinite variety of requests to invocate and it would have to show that every one of them isn't a religion to keep its evangelical skirts untainted.

So Pease is right; the Borough would be far better off getting out of the religion business altogether.  Then all they'd have to worry about is pictures of pyramids in the Homer post office.
