Steyn wrote a piece not too long ago lamenting the coming death of Europe because of low birth rates, and how Europe would soon be Islamic...but then he NEVER mentioned an OBVIOUS solution ...ending Muslim immigration to the Europe/West.
At the end of the day, Steyn is just another pro 3rd world immigration (legal or not) Multiculturalist.
He could mention it, but would anyone actually listen to him? Answer: No.
The fact is that immigration can NEVER be stopped. In many cases, Immigration is good for society (I would tend to think so, after all, my ancestors came here from Sicily at the turn of the last century and I'm glad they did. Ever been to Sicily? Uggh!).
The reasons why immigration (European immigration, specifically) will never be stopped is that a) you tell the Germans they can't have six weeks of vacation, retire at 50 AND enjoy government-paid-for breast enhancement and see how far you get, and b) even if you sealed Europe hermetically, the fact that you've kept every Arab out does not automatically guarentee that Danes, Finns, Begians, and Frogs will begin breeding again.
The issue is not so much immigration as it is culture. That is the entire point of this piece; the cultural dangers inherant in spiralling birth rates.
If the Muslims are breeding at twice the rate of nativeborn Europeans, it doesn't take higher math to tell you that there is no OBVIOUS solution that will prevent Muslim population surpassing the locals in X years.....except deportation back to from whence they came.
Missing that point means that you missed the point of Steyn's editorial on demographics. Mark Steyn is hardly a " pro 3rd world immigration (legal or not) Multiculturalist" as you charge.
