Mark Steyn: Biggest story of our time: our self-extinction

It is often said that "demographics is destiny." Mark Steyn gets on his favorite topic and does it with wit and remorseless logic.

Christmas is a good time not just for Christians to ponder the central proposition of their faith -- the baby in the manger -- but for post-Christian secularists to ponder the central proposition of theirs: that religion is a lot of goofy voodoo nonsense and that any truly rational person will give it the bum's rush. The problem with this view is that "rationalism" is looking less and less rational with each passing year. Here are three headlines from the last couple of weeks:

• • "Mohammed Overtakes George In List Of Most Popular Names" (Daily Telegraph, London)

• • "Japan's Population 'Set To Plummet' " (BBC News)

• • "Islam Thrives As Russia's Population Falls" (Toronto Star)

By comparison with America, those three societies are very secular. Indeed, Russia spent three-quarters of a century under the most militantly secularist regime of all: Under Communism, the state was itself a religion, but, alas, only an ersatz one, a present-tense chimera. As a result, Russians more or less gave up begetting: Slavs are in steep population decline, and, on present trends, Russia will be majority Muslim by 2050. And the Russian army will be majority Muslim by 2015. In western Europe, societal suicide isn't quite so advanced, but the symbolism is still poignant: "George" isn't just the name of America's reviled cowboy president, but of England's patron saint; the national flag is the Cross of St. George, under which Englishmen sallied forth to smite the Mohammedans in those long-ago Crusades. Now the Mohammedans have managed to smite the Georgians big time, not by conquest but simply by outbreeding. Mohammed is also the most popular boy's name in Brussels, Amsterdam and other Continental cities.

But forget Islam: In Europe, they're inheriting by default. There are no Muslims or any other significant group of immigrants in Japan and yet the Japanese are engaging in a remorseless auto-genocide. Already in net population decline and the most geriatric society on earth, their descent down the death spiral is only going to accelerate.

Will Islam take over the earth with the belly if it's women? It's something to be considered.
