I'm fine with the Christian aspects, too. A holy birth in the dead of winter, of a mystical child doomed to die in horror? That's pretty messed up.
This holiday is a fantastical conglomeration of cultures and stories. I love the connection to the sun god Mithras, and the pagan traditions of the solstice, Yule and Saturnalia. Mostly, it just moves me in some primal way, to fight against the darkness of winter, to feast and be merry with those I love, because we might not all make it to spring. *Merry Christmas*.
