What is Christmas?

by InquiringProfessor

Non-religious American here, all of my familial christmas traditions are extremely bizarre: decorate a tree, celebrate a virgin birth, leave out milk and cookies for a chubby reverse-burglar...

How do I make sense of this random madness?!

How did it get like this?!

You may want to ask more specific questions, as each tradition will have a different origin.
