"I have to admit, I don't get the big deal about an ecumenical greeting. I work in retail in a heavily multicultural area, and I routinely say "Have a happy holiday!". People generally smile, and respond, "You too!". I don't see how "Happy Holidays" discriminates solely against Christians--as all three major monotheistic religions have festivals around this time, I see it as a nice way to include everyone--not Disclude someone, as I would be by wishing "Merry Christmas", "Happy Hanukkah", or a "Have a Tip Top Tet!"."
How much money does the retailer make on Kwanzaa, Ramadan, or Hanukkah gifts COMBINED? How much money does the retailer make on Christmas presents? Personally, as a consumer, I want my holiday (Christmas) and my purchasing power acknowledged--not lumped in with all the others (somehow diminishing the power of the Christmas season). Of course, this addresses only the secular reasons; the religious reasons are obvious and go without saying.
