I don't know when exactly it started but you hear most people wish others a Happy Holiday instead of Merry Christmas even when Hanukkah has long past. I've been doing it too. I know there's other religions but this time of the year, this day of December 25 is for Christians. Why can't the words Merry Christmas be taken for what it really means: wishing that person a wonderful day with family and friends, peace, and the strengthening of faith whatever it might be.
Merry Christmas everyone!
