I do what Donald J Trump does....I say: Merry Christmas & Happy Holidays! This way, I get the traditional MAIN holiday in and satisfy the easily offended with happy holidays.
I never say happy Holidays, not even once. It’s just Merry Christmas before the 24th and Happy New year after the 24th..
I’d go as far as, “Merry Christmas and Happy Hanukkah”, but nothing else. Everyone else can be offended; I hope they are.
