Liberty Counsel, a non-profit legal institution dedicated to protecting religious liberties, has published their annual "Friend or Foe" list. This list identifies those businesses which are friendly to Christmas and those companies which are hostile. This would include companies which refuse to decorate with Christmas decorations or have replaced "Christmas" with words such an "Winter" or "Seasonal." Some companies forbid employees from uttering "Merry Christmas."
