Obviously this book has been written over many months. But I think it can only gain traction on the Left now that Obama is in office. While Bush was in office, the Left was busy putting all of its efforts into hating George W. They simply refused to see any threat from Islam. After all Islam is one of the stripes in the multicultural rainbow flag. Of course the culture that Bush represented has never been given a stripe in that flag of color and never will get a stripe.
Now that Bush is fading into a distant memory, the Left will have to face Islam directly. There may be some surprising results in the near future. It is one thing to embrace the Other when the hug takes place only in a book, or through a television screen, or from a stripe in a multi-colored flag. It is quite a another thing to embrace the Other when the call to pray echos throughout your city 5 times a day, and you can't get a cab because all the cabbies are in the local mosque. Some of the Left may wake up to find that the group hug they gave Islam was really a one-night stand and discover that they woke up with Frankenstein in their bed.
The dilemma on the Left is that they can’t resist the Islamic invasion without contradicting everything they’ve been preaching for decades. Of course, this assumes they really want to resist Islam—its quite possible it may all be part of the plan.
When you peel back the onion, the Left has always been after one thing: absolute power. It was true (and obvious) in Stalin’s time and it is true now. The best way to successfully wield absolute power is to totally subvert the individual to the State. To do that, one must tear down the attitudes, values, and traditions that the majority holds dear and replace them with a new, different set. This is a variant on the technique used in military basic training. That is part of the reason why the Left supports things like rampant immigration, Gay marriage, and radical feminism while eschewing traditional Western religions. Radical Islam fits the bill in two respects. First, like the Left, it seeks the overthrow of Judeo/Christian culture. Second, and more importantly, Islamic clerics have close to absolute power over their adherents. If the Mullahs can motivate someone to be a suicide bomber, convincing them to pay higher taxes should be a piece of cake. Many in the Left must salivate at the thought of having that much control over the individual. At some point, the Left will have to choose between radical Islam and the continued embrace of its traditional interest groups (gays, feminists, etc). I predict they will chose the former, because ultimately the Islamists will be more numerous (in 30-50 years or so).
