CNN released a survey of antisemitism in Europe, which I have chosen to link in the context of this essay in Tablet (a Jewish publication, if you hadn't guessed from the title.) I am letting the article speak for itself, save for a few things: I have not dug into the survey enough to get a feel for how much of this antisemitism is from newer Muslim immigrants and how much descended from the longstanding suspicion and hatred of Jews more associated with right-wing parties. Related, I don't get a sense of how much of the antisemitism is passive, a sullen resentment, and how much is active, including a desire to hurt or remove Jews.
I was not surprised to see such high numbers for Sweden, as Malmo is now quite Muslim (over 50% of schoolchildren) and Stockholm is seeing the increase now. However, that will not be the whole picture as well, as it used to be said "scratch a Swede and find a fascist" long before they encouraged significant immigration. "Fascist" is too strong a word, but the reality is on that road. Like many northern European nations, Swedes have prized all pulling together, being one people. This is not unrelated to their strong social safety net. However, this fondness for at least a mild "socialism for the nation" is not that far from "national socialism." They are not the same, and I am not claiming it. They are decent people trying to do well and be kind. Yet the two are related - hence their WWII neutrality and complete penetration of intelligence services by Nazis and communists both.
Thinking of Malmo and Stockholm led me to the fourth observation. Jews in Europe have long lived in the cities, and recent immigrants come to cities as well. I wonder what the numbers are like in the countryside. Perhaps it doesn't matter.
