That's paradox because I see Americans as ancestors from Europe. Italians, Germans, Irish, etc they had literally nothing to eat so they emigrated to the US. Let's not start about English who are basically Germans hence slavery and exterminating native Americans. Also how many criminals were sent to America...

But ok, there's one thing about Russian women. You see after WW2 many Russian men were not there. Killed by Germans mostly. And there were many Russian women. And they had to find man. So they had to be extra pretty. There's theory that this attitude stayed until today. So that's why people see Russian women as easy. Maybe.

Btw when we're at theories, there's also one that grandchildren of SS soldiers and also concentration camps survivors, have consequences even today. One could say mutants?
