FTW. Happy Holidays and Merry Christmas are not mutually exclusive. One is specifically aimed at Christmas, the other to cover the entire holiday season; Thanksgiving, Christmas, New Years, Hanukkah etc....
I swear, sometimes people are so ready to be offended they make up sh$t to be offended by....and that offends me dammit! LOL.
Bingo!
People have been saying Happy Holiday for .... decades?
...why it suddenly became an insult to baby Jesus to say it, I dunno.
EDIT - But it just occurred to me... Baby Jesus KNOWS I don't mean any insult to him, so.... he's the only one who really matters, right?
