And it seems to me like that culture is being imported from the US to the rest of Europe, with the exception of, as far as I know, Eastern Europe.
You are wrong about that. Eastern Europe is even more susceptible to American culture than many old European countries, of course Scandinavian countries don't fit among them because they never were historically influential enough to have any pride or sense of accomplishment like Italian, Spanish, French, German or English.
Thing about former Soviet block countries aka Eastern Europe is they trail by few decades by developed countries so this gay/feminism/sjw thing still haven't hit hard and started changing the way general populace think although there are efforts by groups and individuals to make that happen.
And I certainly don't get why you Scandinavians are crying so hard about this issue when everybody else knows you've traded your culture decades ago to become artificial societies moulded by big and influential countries as they see fitting. There is a good reason why French and German do not want to learn English even tho it is mandatory today. They have strong national pride and don't understand why ginger uglies with rotten teeth should be the ones whose language will become new global language. On the other hand we have Dutch, Danish, Swedish, Norwegian and Finnish, all of you who speak perfect English like it's your native language. You've embraced it fully, not just language but entirely culture, mixed with neosocialism.
I'm certainly more sad about fall of once great Argentine than I'm worried about lifeless, perpetually frozen lands of Vikings. Just like in case of sand friends, nature is telling people where they should and where they shouldn't live. Which is why there is little natural empathy when it comes to certain parts of the world, like deserts and frozen tundras. Drop an atomic bomb on the Iraq or northern Finland, world will care a lot less compared if you do the same in some populated part of the world that has nice weather conditions throughout the year.
Edit: What Angantyr is showing isn't Swede culture, it is Sweden moulded by German culture of the Third Reich era. Sweden don't have such thing as their own culture for a long time. Country lost in translation, which is why this is happening right now in Sweden.
