Knowing the holiday and the motivation of this Rabbi, I would assume he would ask for a Menorah also in the absence of any tree.
The Rabbi has every right to file suit if he chooses.
He is not suing to remove the trees. I doubt he and his organization would be suing to remove any Christian display.
To defend themselves, the Airport choose to remove the trees.
Put the blame where it belongs. If the Airport believed it had a case to deny the Menorah, it should have called the Rabbi on the suit. If it didn't, why did it deny the Menorah?
A Menorah is not contraindicated for Christmas. There would have been no Christmas but for the story of the Menorah and the Books of Maccabees is a Catholic Deuterocanonical book.
The Rabbi had every reason to believe the Airport would respond as have numerous entities in the Nation. No one reasonable would have expected them to go nuts.
He's just loaded with rights. I don't know if you noticed (the Mel Gibson story so overshadowed this event) but a prominent Jewish lady in SEATTLE was murdered many weeks back by what looked to me, at least, an Islamic terrorist.
Airport? Like in LA? Airport? Like where all these Islamo-nuts seem to love to stage their antics?
You're darn tootin' I wouldn't allow a Jewish candle-lighting ceremony in this public and dangerous venue to take place. It'd be totally stupid. Much more provident to remove the trees.
The Rabbi has every right to file suit if he chooses.
