Swedes have been, for centuries, a very homogeneous society, of one language, mostly of one religion, and almost exclusively of one Nordic racial demographic. And no, not all Swedes are tall, strapping blue-eyed blondes, many of them are of brunette or red hair coloring, and have eye colors that range from green to hazel to gray. But they are all definitely Nordic.
Now, suddenly there descends upon their country persons of African and Middle Eastern origin bringing with them a strange religion and customs of which they have never had contact before. And all demanding services that the Swedes have worked out for a relatively small part of their population that through some misfortune, had found themselves unable to fully provide for all their own needs.
None of the new people bring any skill sets that can be used to advantage within the Swedish communities, and also a multitude of diseases and collected mischief-making practices that do not augur well for polite communal relations. Theft, rape and just plain bullying tactics are visited upon the rather pacific and phlegmatic Swedes, and at first, they are at a loss to comprehend.
But remember, their ancestors include some of the most warlike people north of the Mediterranean, who managed to terrorize their neighbors for centuries, and were feared and respected as far away as Spain and even parts of the Russian hinterlands, where they sailed their longboats up the Volga, sometimes transshipping to the Black Sea.
Catch the herring, clean the herring, cook the herring, raid France.
Problem is, many of the Swedish Vikings emmigrated to places like Normandy, Britain, Ireland, Russia, etc., where they conquered kingdoms for themselves and settled down.
Many of the rest of the warlike Swedes were killed fighting for Gustavus Adolphus in the 30 Years War or fighting against Peter the Great.
I hope they find the spirit to fight back again. I hope all Europeans and Americans do.
