black santa. but instead of giving, he takes and murders.
Just like the original Odin "Santa Claus". That's the origin of "You better not pout...". Kids were terrified of Santa Claus. He was said to take away bad children. If children behaved, he would reward them. The song attributes all-knowing powers to him. It's basically idolatry. Even to Christians, the origins would be considered idolatrous. No real Christian leader would say that the pagan origins of Santa Claus has anything to do with Christianity. Saint Nicholas is a different story. He was a Christian saint who is personified by Santa Claus nowadays. To say Santa Claus knows all and takes part in reward and punishment is to deify him. So basically Santa Claus and his elves are a replacement for G-d and angels in the imaginary children's "theology".
When kids find out their parents lie to them about Santa Claus, they might think "G-d is a lie too.". I think I've heard Christians say that as well. So rather than believe in their religion that teaches their messiah was born on that holiday, they reinvent it into idolatrous childhood fantasy.
