I have argued about the reasons for anti-Semitism. I have cited Norway as a unique exemplar in Europe and Scandinavia in its high level of anti-Semitism. Here is the latest outrage: a Norwegian foreign service officer is openly, publicly, a Jew hater.
Norway is a unique exemplar for two reasons that support my thesis about anti-Semitism. Norway has very few Muslim immigrants which is the false reason often given for the anti-Israel position of other European countries. Norway is anti-Israel with virtually no Muslim immigrant population.
Norway has the most blatant and well establish hereditary upper class in Scandinavia...which supports my thesis. The hereditary upper class uses anti-jew hate as a distraction from attention paid to the hereditary upper class.
PS To get a sense of how bad jew hate is in Norway check Dave's comment below and the citation he gives. Its shocking.
