Tommy Robinson's carol concert claimed to be "putting Christ back into Christmas". Church of England Bishops quickly pointed out that Christ never went away and warned about Christmas becoming another proxy in the culture wars. Many of Robinson's supporters are turning to Christianity. Some have openly stated that the Christian faith is a cultural ballast, representing British freedoms and values, and a defence against a perceived threat posed by Islam and immigrants. For others, Christianity and Christmas is being appropriated in the most un-Christian way, the Holy Family were persecuted refugees, and a central message of Jesus was one of radical hospitality for the stranger.

This year, Christmas comes at the time of a wider debate about so-called "civilizational erasure" in Europe, following the publication of America's National Security Strategy. It boldly states that, within a few decades, NATO members will be "majority non-European", encourages the resistance - and praises the influence - of "patriotic" European parties, including Alternative fur Deutschland (AfD) in Germany, a far-right anti-immigration party.

Is a full-throated defence of Christmas a sign of strength or weakness? What's the bigger threat to Europe: "cultural erasure", or far-right populism?
