What about Hanukkah?
I don’t mind a “Happy Hanukkah” sign. I wish my Jewish friends a Happy Hanukkah every year. None of them seem to get all bent out of shape if they hear “Merry Christmas”.
But the war against Christmas is largely driven by secularists, and they cover their tracks by insisting they only want to downplay Christmas so as not to offend Jews or other religious minorities.
