Almost everyone I've come into contact with has said Merry Christmas. I've rarely heard Happy Holidays.
Happy holidays feels kinda forced imo. if you’re in question about whether the person you’re greeting will be upset by your greeting, it’s probably best just to not say anything at all.
I start saying Happy Holidays around Thanksgiving until New Years
Too many Holidays in between just get em all out the way
merry christmas
happy holidays are for psychos
