Mr Dawkins can answer for himself. But, leaving aside the cultural and aesthetic considerations, I can tell you why a Taoist sings carols.
New birth in the midst of winter darkness. It's a potent symbol.
Christians know this, of course, but they have never been the only people who do. The image possessed 'deep meaning' centuries before Christianity existed. It's a Taoist idea, too, and a Buddhist one, and a Jewish one, and a Hindu one. It should come as a surprise to no one to discover that the symbol retains power in our own time, inviting contemplation beyond all lines drawn by dogma.
No one can copyright an insight.
Speaking of which, Linda: December 25 just arrived in my time zone.
I wish you a hopeful Christmas
I wish you a brave new year
All anguish, pain, and sadness
Leave your heart and let your road be clear.
Peace and good tidings to all.
