Are Norwegians and Swedes rivals in Europe as well as here in America ??
Swedes are for Norwegians what Yanks are for Canadians I think. We're their "bigger brothers", which they don't always like...My home province was ceded from Norway to Sweden in 1658, by the way.
Here in America, especially in states like Minesota and Wisconsin, many Norwegians and Swede's settles there. They formed town around their own ethnicity and developed rivalries with neighboring towns.
I dated a girl from that area who was Norwegian. She said she couldn't get out of he car in a Swedish town without the risk of getting beaten up for being in the 'wrong' town.
Funny. They seem to hold grudges from the old days, that are forgotten here in Europe. The only day at the year that I would be afraid to be in Norway as a Swede would be on Syttende mai, 17 May, their national day. That's the only time when they might be really anti-Swedish.
--Or if Norway and Sweden ever have to face each other in the World Cup, and Sweden winds up winning on a technicality, or referee error.
For the record, I lived in Eastern North Dakota when I was a kid, and the Ethnic situation was pretty much Norwegian, Swedish,Danish with a few Finns, Poles, and Ashkenazi Jews. There were no ethnic tensions there whatsoever. --Everybody was properly Scandinavian and culturally speaking, they were completely boring.
