For those who believe in Christmas, please be generous and kind to those who don't. The Tao Te Ching says that a bad man is a good man's charge.
It is not necessarily the case that those who don't believe in Christmas are bad, just as it is the case that those who believe in Christmas are not necessarily good.
The mirror was invented for this reason.
Thank you and Merry Christmas to you and all those you love and care about.
