You really gotta laugh at these atheists who have no idea what Christmas or Christianity is about, and are not shy about demonstrating their ignorance. They apparently think they are sanitizing the religion out of Christmas by getting rid of Santa Claus. I don’t remember Santa Claus at the Nativity. Next they will tell us we’ve gotta get rid of the Easter Bunny.
Lots of other folks weren't there too including Matthew, Mark, Luke and John. Suggest you read up on "St. Nicholas" and his transition from Greek Νικόλαος ο Θαυματουργός through the Dutch Sinterklaas to our Santa Claus. Most thoroughly Christian.
Though it's in a way an embarrassment that, more and more every Advent season, I'm told how much I look like Santa Claus. Small children now regularly see me that way -- boarding a recent flight a little girl lit up and excitedly waved at me; what could I do but smile and wave back?
Hm. Maybe they'll eventually try to ban me.
