This is how Megyn Kelly handled a story by a black woman who wrote that maybe, just maybe, Santa doesn't have to be white all the time (because—spoiler alert—Santa can be all things to all people!):
For all you kids watching at home, Santa just is white. But this person is maybe just arguing that we should also have a black Santa. But, you know, Santa is what he is, and just so you know, we're just debating this because someone wrote about it, kids.
For good measure, she also assured the children that Jesus was white too—something that is far from a settled question.
