It's hard to deliver a wake-up call for a civilization so determined to smother the alarm clock in the soft fluffy pillow of multiculturalism and sleep in for another 10 years. The folks who call my book "alarmist" accept that the Western world is growing more Muslim (Canada's Muslim population has doubled in the last 10 years), but they deny that this population trend has any significant societal consequences. Sharia mortgages? Sure. Polygamy? Whatever. Honour killings? Well, okay, but only a few. The assumption that you can hop on the Sharia Express and just ride a couple of stops is one almighty leap of faith. More to the point, who are you relying on to "hold the line"? Influential figures like the Archbishop of Canterbury? The bureaucrats at Ontario Social Services? The Western world is not run by fellows noted for their line-holding: look at what they're conceding now and then try to figure out what they'll be conceding in five years' time.
