Baby Jesus, the loosing rival of Santa and the Coca-Cola corp, is fine in my books. Tradition, culture, church and childhood aside, there's plenty other symbolism in the nativity which the kiddy-fiddling, over-fed, ever-hungry, uber-commercial jolly old saint nic lacks. Take the sheep(herds) for example - reminder of drought-stricken rural australis? Or the property boom? (no room in the inn) The ageing population? (babies), GPS innovation by wise men? Teenage pregnancy? Arial Sharon's health scare and his now 'Stable' condition (stable, xmas - that sly dog) And surely we dont have to mention the middle-east (what's going down in Bethlehem 2005yrs later?) Why should Islam have any beef(/pork) against the birth of the prophet Jesus?
Point is that the nativity means something and sparks discussion. Id sooner accept a few casualties to heated debate than loose the whole nation to the economy.
