Well, related to my last post, there's always Dawkins. It's pretty nice, and this is very generous of him:
For better or worse, ours is historically a Christian culture, and children who grow up ignorant of biblical literature are diminished, unable to take literary allusions, actually impoverished. I am no lover of Christianity, and I loathe the annual orgy of waste and reckless reciprocal spending, but I must say I'd rather wish you "Happy Christmas" than "Happy Holiday Season".
On the other hand, I doubt I'll be wishing anyone a good Newtonmas this year...
