"...You can see the problem that then develops when people from the in-your-face end of the gradient immigrate to the feel-your-pain countries. When immigrants bring their Middle Eastern hostility and assertiveness, the natives in the northwest are reluctant to vocally protest right back at them, because, well, it's just not done. They just give them That Look that causes their fellow Northwest Europeans to feel guilty that they've caused their neighbors discomfort. But it doesn't work on the Middle Easterners. They just see the failure of the natives to do anything substantial as proof of their bland white bread inferiority."
This is true. We do That Look that makes queue-jumpers shuffle guiltily to the back of the line, and we're still kinda surprised when it doesn't work on Islamonazis. Or even Poles.
