This claim of the 'new war' does make me ask some other questions though. Who is really leading the war against Christmas and who is fighting for Christmas. I think I would claim that in some ways it is the same people who are fighting on BOTH sides.
I don't think that the Christian communities can with any degree of honesty claim that the modern Christmas has much to do with their faith for most people. It would be highly disingenuous to try that argument.
Let's face it, the commercialisation of Christmas was completed many decades ago. To paraphrase Tim Minchin's great song "White Wine in the Sun", a dead [and mythical] Palestinian has found himself press-ganged into selling Play Stations and beer. It is obvious that the main thrust of the Christmas message these days revolves around commercialisation. Businesses rely on the excessive Christmas spending for their very survival.
The tradition of the tree is ancient and pagan, and Santa doesn't even have a place in the polytheistic pantheon of Christian 'deities' alongside God, Jesus, something godly and intangible called the Holy Spirit, and Mary. Whichever of the particular sects of Christianity you choose to prefer, none of them include the character of Santa. Perhaps this is because of the simple fact that there is too much evidence for the existence of Santa and that he therefore cannot be considered to be sufficiently god-like.
Even the really ancient parts of the Christmas tradition - such as the choice of the date of Christ's birthday - were stolen from previous traditions. The time of the solstice had ancient significance, but 25th December was stolen directly from Mithraism in the Roman world when Constantine chose to change religion - for whatever political reason seemed expedient at the time.
All in all, I think it is much too late to cry that there is a war on the Christian version of Christmas now. I accept that rational voices have the power to communicate with each other world-wide for the first time in history and the confidence of the Free Thinking movement is growing, but for most people, the spiritual version of this holiday has gone, long ago. Whilst it is sometimes dressed up as a nice story for the children, it is important that those children don't find out too early about the disgusting 'scape goat' philosophy of Christianity.
We wouldn't want to spoil their Christmas, would we?
