I’ve been putting “happy holidays’ on all my Christmas cards for a few years now. I’m going to write Merry Christmas from now on. I have a lot of Jewish friends and if any of them get offended, they can complain to me and I’ll take them off the damn list. It’s my small part, but I’m sick of it too. MERRY CHRISTMAS!
I can't speak for anyone else, but being Jewish, I've never been offended by someone saying "Merry Christmas" to me. If it's a stranger that doesn't know I'm Jewish, why should I be offended. And I'm not offended when someone who DOES know I'm Jewish says "Merry Christmas." I happen to like going to Christmas parties.
I always make it a point to say "Merry Christmas," especially if someone wishes me "Happy Holidays." In fact, it happened just yesterday, and the person's face always lights up with surprise and happiness when I return the "Happy Holidays" with a "Merry Christmas."
