Norway is a beautiful country with some of the most beautiful women in the world.
Norwegians are also among the most smug, self-satisfied and narrow-minded people in the world. The Norwegians think their way of doing things (mostly a socialism based on envy) is the only way and look down their noses at everyone else.
Without oil, the country would still be poor -- before oil its leading industry was shipping and its leading exports were people and fish. (In the 1920s there were more Norwegians in Brooklyn than in Oslo.)
You can apply this to just about every ethnic group. It doesn't explain why there would be any feelings about Jews one way or the other.

Wouldn't that make them look favorably on liberal groups?
