Age + Welfare = Disaster for you;
Youth + Will = Disaster for whoever gets in your way.
By "will," I mean the metaphorical spine of a culture. Africa, to take another example, also has plenty of young people, but it's riddled with AIDS and, for the most part, Africans don't think of themselves as Africans: as we saw in Rwanda, their primary identity is tribal, and most tribes have no global ambitions. Islam, however, has serious global ambitions, and it forms the primal, core identity of most of its adherents -- in the Middle East, South Asia and elsewhere.
Islam has youth and will, Europe has age and welfare.
As usual, Mark Steyn has nailed it. It ain't pretty, but it's helpful that at least someone's got the guts to write it. CAIR is all over it, of course, issuing their version of a fatwa against Steyn over this essay.
I'm telling you folks -- this is life or death here. There's no middle ground. You're either going to wake up and stand up for civilization, or you're going to lie down and continue to pretend nothing's happening. There are some things worth giving one's life for... worth standing one's ground for. And there are a lot of lazy Westerners who don't understand this. That scares me more than the Islamofascists do.
