Many people over many centuries have tried to understand the root causes of Jew hate.
I have succeed. I have found the two elements that, when joined together, explain cross cultural differences and within culture differences.
The issue is merit.
Wherever Jews are in the active commercial world, they provide a major social challenge because they promote merit. The society must find a way to deal with this meritocratic-demanding population.
As I have pointed out in the past, societies that have strong inherited social class structures are particularly subject to Jew hate. I have also pointed out that Jew hate is a class of paranoia and significantly disables the people and societies that have this brain disease.
I have finally realized that these two observations fit together. Societies that have strong hereditary social class structures are threatened by meritocracy.These societies promote paranoia as a way to describe the disruptive presence of Jews, with their merit. Promoting Jew hate paranoia is the mechanism that hereditary class societies use to support their upper class survival.
There are several societies where this is not the case. In the United States (and to a lesser extent in Canada) hereditary social classes disappeared in 1960 at the same time Jew hate diminished rapidly.
In Japan, China, and Hindi India, Jew hate has always been minimal. In Holland, Denmark and Finland Jew hate has been minimal for a long time because these are non-hereditary social class societies. In Sweden, where an effort has been made to diminish social class, Jew hate is limited. In Norway, where Jew hate is strong, hereditary social class is also.
Japan, China and Hindi India have 2000 year old social class structures that have mechanisms for accommodating merit. Therefore, Jew hate is not necessary.
Jew hate is dominant in the rest of the world: Latin America, the remaining parts of Europe and nearly all of Arabia and South East Asia. In Southeast Asia, the Overseas Chinese are the Jews.
In Malaysia we have a nearly perfect case. There are virtually no Jews in Malaysia or in adjacent Singapore. In Malaysia, which only joined the commercial world after World War II, the government and the ruling class have deliberately created Jew hate. In Singapore, Jew hate is absent because the population is primarily Overseas Chinese.
The largest landmass with little or no Jew hate is sub-Saharan Africa (excluding South Africa). The reason is straightforward: modern commerce has not developed. Meritocracy in a non-commercial world doesn't exist and is therefore not a challenge requiring Jew hate.
Final evidence: the far left in the United States and Canada has a case of Jew hate. The reason is that these people support an anti-merit ideology that worships government jobs and unions. These are two environments in which merit is irrelevant. Only seniority matters. Consequently the far left love of government and union jobs is reason for Jew hate. Jew hate is hatred of meritocracy.
Your comments are welcome on this centuries old issue.
