Here is a follow-up on that fiasco a day or so ago at the Seattle-Tacoma airport, where a (I'd argue) well-meaning but misguided rabbi hoped to get his own particular religion acknowledged and instead ended up having all holiday decorations removed.
According to the article, the Christmas trees have been put back up and the (I imagine repentant) rabbi decided not to sue.
Also notable, there is a 1984 'Reindeer Ruling' that states that any symbol that is mostly secular (like a reindeer or a Christmas tree) is not a violation of separation of Church and State (refraining from comment), and so our well-meaning rabbi wouldn't have had a case, anyways.
All's well that ends well, I suppose. Like the article's author, I hope this is a sign of an upward trend out of this unreasoning political correctness.
