There is a difference between an individual using "Happy Holidays" as a genuine wish of goodwill versus its systematic replacement of "Merry Christmas" by institutions for no reason other than to appease the gods of diversity and political correctness.
The vast majority of people in this nation celebrate Christmas in some manner. Anyone who gets offended by seeing the phrase "Merry Christmas" at the local dept store is the type of person who goes out just looking to get offended by something. They are they type who can't stand it that their warped sensibilites are offended by a display on behalf of the majority. They are contemptible. But its most likely the case that most people who don't celebrate Christmas or believe in Jesus probably don't think twice about seeing displays of the word that signifies the entire meaning of the season, w/o which there would be no holiday season. Therefore, there is no reason for this insanity as Macy's was in no danger of losing business if non-believers were subjected to the horror of having to actually see the word "Christmas" displayed.
Well said!
