@ingliz he ignores mixed-race people with unpredictable results of the kind that does not fit the Nazi neat package criteria.
The mixed race people are out there and according to the information I already presented are going to increase in the future. Simply because it is easy for people to travel, and communicate. For example Ingliz you are in Malta and I am in Mexico. But we can communicate here and through emails and private messages, etc. Easily.
Can even do video calls. So human communication is rapid and instant now. Most people used to meet through dances, bars, churches, schools, jobs, and so on. Locally. But people are doing a lot of stay-at-home work and now they can date online or meet people from all over the world. Even language barriers can be overcome now with AI programs that do instant translations and interpretations.
So what happens now and in the future? A lot of people might like marrying people who are very different than they are. In terms of looks, skin color, hair type, and even language and culture. The truth is one should marry someone who shares the same VALUES in life. Not necessarily the same phenotypic look or somatic looks, or even the same ethnic background, or language or cultural matrix. But the same value system. That works.
For some people, religion is the primary thing. Two Roman Catholics who are serious about RC values fall in love and marry eh? Like Mexican RC women and Haitian RC men. One Mexican indigenous and Haitian French Creole-speaking man who learned Spanish in Tijuana and he shared the RC value system with his Mexican wife. They have kids and live in Tijuana. He tried to get to the USA but it got complicated. He wound up getting a job as a teacher in Baja California Norte and that was that. End of the story. New genes in the pool in Mexico.
It will happen that way in the US, Europe, Africa, and every other continent including Australia and even the Scandinavian nations where the Nazis wanted to remain pure and so on. They wind up with refugees from many other nations and the ones there start speaking Swedish and other languages from the neighboring Nordic nations, and voila, even they get the mixed-race children whom the Nazis have a hard time saying that the neat package is the norm and the only thing that is worth rallying around.
Again, values are inherited through your parents. Or taught socially and culturally and have some kind of individual basis? What are family values, and cultural values? Are they fixed for all time? Or do they change constantly through generations? If they change? Then is it possible to have mixed-race progeny and mixed cultural and value systems within families that produce fertile offspring in future generations?
That is what would be interesting.
But if Nazi thinking in the Twilight Zone continues to ignore that mixed-race people exist and are increasing? Then where is he left in his limited boxed-in scientific racism theories? Nowhere. So he ignores it.
Or he can say, 'Those people do not count. They violated the sacred rules of having sex with your own kind only.' Can you tell who is racially pure just by looking at their faces and bodies? That is the issue with the racists. Genes are funny that way. You have to examine beyond somatic looks to get to the DNA story. And peoples' DNA stories are not that neat. They never have been.
