We are all descended from invaders

Nat. Geographic reports:

Now scientists are delivering new answers to the question of who Europeans really are and where they came from. Their findings suggest that the continent has been a melting pot since the Ice Age. ...

In an era of debate over migration and borders, the science shows that Europe is a continent of immigrants and always has been. “The people who live in a place today are not the descendants of people who lived there long ago,” says Harvard University paleogeneticist David Reich. ...

In Britain and some other places, hardly any of the farmers who already lived in Europe survived the onslaught from the east. In what is now Germany, “there’s a 70 percent to possibly 100 percent replacement of the local population,” Reich says. “Something very dramatic happens 4,500 years ago.” …

“To me, the new results from DNA are undermining the nationalist paradigm that we have always lived here and not mixed with other people,” Gothenburg’s Kristiansen says. “There’s no such thing as a Dane or a Swede or a German.” Instead, “we’re all Russians, all Africans.”

The nationalist paradigm is that a nation must defend its borders, or else it will be wiped out by invaders.

The DNA results prove this. Become a fierce nationalist, or be exterminated. That is the history of Europe.

All I hear from Democrats today is that they want to replace the American White population with non-whites. There is not even one Democrat presidential candidate who has a policy position to put limits on non-white immigration.
