I have no problem with anyone following any religion they choose - in my experience, people of faith are made happy because of it. But there is no place for modern government in upholding any traditions of any faith, including Christianity. It's survived 2000 years so far, and faced worst problems than some shops not wanting to selling cards with the name of their second-most important festival on the front.

Is there some reason, given so many people apparently care about this and it's not actually breaking any laws, that Christmas card and Advent calenders aren't still made?
