In the small southern town where I grew up the Jewish merchants had no problem with having their newspaper ads with Santa Claus and the words Merry Christmas. While the stores didn't have the nativity in them. There were decorations that had Merry Christmas on them. Most of those same merchants had ads that wished their customers Merry Christmas and a Happy New Year in the Christmas day addition of the paper. Granted they were a very liberal synagogue, but it was never an issue. If the leftists have their way I doubt that most Americans will get all that enthused about buying presents to open around the Yule Log. If Christmas goes a lot of small merchants who depend on the Christmas season for their yearly profit will go out of business.
Not surprising. On one of my first jobs, the old Jew who owned the place LOVED Christmas, at least the trappings and secular aspects of it. The place was decorated, had a Christmas party he paid for out of his own pocket, and he liked carols, also. And in an entriely different industry, my wife also had a similar experience with another Jewish boss.
Jesus was a Jew. Judaism may doubt He was the "Real Thing Yet", but that does not mean they had to hate Him.
I see lots of menoras around on display. Nobody complains. So, what's wrong with a christmas tree?
