Was it a Star of David, or an Israeli flag patch?
Not that it makes any difference. But I'm just finding it funny that no one is "provoked" by the flag of Norway. Doesn't it have a cross on it?
The picture of the young man on the Dagbladet site shows him wearing a (not wholly accurate) reproduction of the Israeli flag, although the picture identifies it as "jodestjernen"--"the Jewish star."
