I celebrate Christmas, and therefore I say Merry Christmas. If I know someone celebrates a different holiday, I will express a sentiment that reflects that holiday, and yes, I even do say “Happy Holidays” on occasion, although that to me is the least personal phrase out there. I do not believe it is the actual words that are spoken, but the sentiment behind the words. However you say it, it comes out of love and peace and wishing good tidings onto others. So, Happy Channukah, Feliz Navidad, Buon Natalie, Joyeux Noel, Froelich Weinachten, Mele Kalikemaka, Happy Eads and Merry Christmas to All, and to All, a good night.
