The response from Turkey has been about as hostile as one would expect.
The response from some members of Germany's Turkish community? To protest outside the Armenian embassy in Berlin.
Out of morbid curiosity, how is the Armenian genocide issue perceived in Europe, in the European press and in public opinion? I suspect that the Turkish government's overreaction is turning out to be a spectacular own goal (or two, or three), inasmuch as the sight of a country fully engaged in historical negationism isn't likely to recommend it for membership in a political Europe that has passed laws against genocide denial. Is it being used to justify pre-existing anti-Turkish sentiments, or is it actually changing the minds of people who once thought Turkey deserved to be an EU member-state?
