Christmas originated... as the celebration of the birth of Jesus.
No it didn't
Every aspect of Christmas, from the spiritual claims, to the secular ways it's celebrated, was taken from the winter time celebrations of cultures that came before Christianity.
Jesus's birthday was thrown in there to make it "Christian" when Jesus wasn't even born anywhere near December
If people want to celebrate it as a Christian event, they can go ahead. But people who whine "don't take the Christ out of Christmas" are obnoxious because their religion doesn't own the holiday, and Jesus wasn't even in there to begin with
That was more of a rant than something directed at you but whatever
