Does Sweden have a single Canadian there under 'asylum' policies?

Yeah, sure, people probably wouldn't care if they were Canadian, because they wouldn't be committing crimes at far higher rates, wouldn't be pushing for more religious rule, and the majority wouldn't be on welfare. That's not what's happening though.

As for your second paragraph - do you really think the governments of the countries these people are coming from are any better? Should every US citizen that wants be able to immigrate to Afghanistan and take a good portion of their GDP as welfare? What about Japan? Should US and Chinese citizens be able to move there if they want and relatively quickly become the majority, right? They need the population, no?

I certainly don't agree with a lot of our Middle East policies, but that doesn't mean European governments should throw open their doors to mass migration. Governments are supposed to exist to help their own citizens. Sometimes that means bombing someone. Sometimes that's the right thing to do, sometimes it's not, but it's pretty damned clear mass migration from third world countries isn't helping their citizens.
