Which continent's immigrants are the main part of North America's population?

Australia and the United States mainly accept white immigrants! Because Spain had a small population a hundred years ago, most blacks in South America and North America arrested hundreds of millions of blacks. In the past, more than 100 million slaves died in the United States. This used to be the territory of the yellow race, but for hundreds of years, more than 60 million yellow races were killed by white people! Now there are less than 20 million Mongolians (Indians), and most of them are already mixed-race. The real yellow Indians are at most three or four million!

At present, immigrants in the United States mainly come from Europe, and there are strict restrictions on other races!

In order to make Australian whites the main body, Britain only accepts white immigrants. At that time, Germans were discriminated against in Europe, but Australians welcomed them, so many Germans found jobs in Australia! Before the 1980s, Australia and New Zealand banned immigrants from other races, and only after the 1980s did a few people open up, because they wanted to maintain the dominant position of whites in society! After World War II, Britain's wages were low, but British colonies such as Canada, Australia and New Zealand really lacked labor, and their wages were three times that of Britain. So after World War II, millions of British immigrants moved to these three places! Of course, I also accept other white Europeans!

As for how to distinguish white people, it is actually very simple! There are black people in Africa, yellow people in Asia, brown people in Southeast Asia, Indians who look like Arabs, black people and yellow people, Arabs with black hair but rough faces in Europe, and whites mixed with Arabs in Spain, Italy, Portugal and South Europe. Some of them have black hair but their appearance is still white in Europe. They are orthodox Germans, that is, white people with blond hair, blue eyes and white skin, that is, Germans, Britons and northern French! Eastern European whites and many Tatars, Gypsies, Arabs, etc. have had mixed blood, basically not as orthodox as German whites!

Whether in Australia or America, the yellow race there may be assimilated by other races for thousands of years, but it may take 10 thousand years to assimilate black people! Because there are hundreds of millions of black people in America! And they have a high fertility rate!

For example, in the past, there were many tribal peoples in Japan, and there were people with darker skin on the islands around Okinawa, but after more than 100 years of mixed blood, their looks have basically been assimilated by Japanese yellow people!
