Hie yourself off to the Wall Street Journal online and read this splendid piece by Mark Steyn: "It's the Demography, Stupid: The Real Reason the West is in Danger of Extinction." (You can find another link on Real Clear Politics). Mr. Steyn says, in substance, that if our Jihadist enemies win the present war, it will be our own doing.
Time constaints, for the moment, forbid much of a discussion, but the article is liberally salted with little gems like this: "Multiculturalism means your kid has to learn some wretched native dirge for the school holiday concert instead of getting to sing 'Rudolph the Red-Nosed Reindeer' or that your holistic masseuse uses techniques developed from Native American spirituality, but not that you or anyone you care about should have to live in an African or Native American society. It's a quintessential piece of progressive humbug."
