I believe there are TWO root causes for Europe's DIATHESIS FOR DHIMMITUDE:
According to Ms. Ye'or, this Arab/European alliance was motivated primarily by anti-Americanism, anti-Zionism and a desire to import oil and cheap labor. ... any Europeans agree with Said’s theories. Many don’t believe that their culture is worth preserving. ... The policies of the EU towards Israel mirror Arab policies. ... This multicultural 'alliance' is currently cemented by European fear of terrorism. ... Europe seems to accept its current dhimmi status, and does not seem to be willing to defend traditional Western, Judeo-Christian values.
(1) EXHAUSTION - they are worn out by the bloody 20th Century.
(2) This exhaustion has led to flase rationalizions and self-defeating modalities which now permeate NOT only the European "Academe" and the elites, but Europe's masses:
As Seinfeld once humorously noted (paraphrasing): the French fought harder to keep out Disneyland than they did the NAZIS!"(a) colonialism and imperialism were bad and their wealth is the result of pillaging the Third World - which would be wealthy if it weren't for European Hegemony. This has caused MASSIVE GUILT and SELF-LOATHING.
(b) nationalism and etnocentricity led to a lack of acceptance of neighbors and bloodshed; therefore we must blindly accept anything that another nation or culture does that is value-related or we risk more pointless bloodshed. This has led to Pan-Europeanism and to Cultural Relativism and to a "Neo/Quasi-Pacificism."Weirdly, (a) and (b) have led them to embrace and adore Third World culture and immigrants even as they try to protect their culture from so-called "savagery of American Cultural Hegemony" - (which is a misconception of and misnomer for the world's freely evolving "Mass/Pop Culture" or the "free marketplace of ideas," which is free because it is unfettered by snobbery and elitism - and which I blogged about here).
