I don't feel a lot of sympathy for Germany being unhappy with foreigners. I remember someone once telling me that the history of Europe is essentially 2,000 years of "the German problem," with its tribes constantly getting frisky and invading westward, southward and, eventually, eastward.
That said, seeing Germany move rightward is not a comfortable feeling. Given a choice, I'd much rather put up with a bunch of self-righteous moralistic Greens than a bunch of self-righteous angry Browns. The latter can lead to trouble.
