So today as an experiment, I had a busy social day, all over the map, DMV, Insurance, office, Bank, various shops and a Pub, being my social self, I mixed it up and went with both, Merry Christmas and Happy Holiday and often, gotta tell, nobody said shit but a word in kind. It was a great day. This is an imaginary war they created to give them self importance and something to bitch about. It's like a portion of the population needs a snickers. I'vr just always used "Happy Hollidays" as an all around greeting encumpassing the festive season, not just one day.
