I think I agree with AnIrrationalRatio. He sent me a message today after I posted the above video:
Wishing someone a happy Christmas/Hanukkah/Eid/Solstice/Tuesday/Birthday/Valentines day/[whatever] is all about the expression of well-being and happiness that you hope or the other person.
You can’t exactly maliciously wish someone a happy Christmas.
So happy Christmas, everyone!
Also, Resolution #4:
Start on Christmas in November.
