That underlying piece of logic is:
There is a fundamental wrongness in Africans and a fundamental rightness in those on the Asian continent and their Diasporas.This of course cannot be true if all humans came from the same seed.
Therefore, the only way this can be believed is if there is logic that comes after the logic of human origins to cause a separation.
However, since Africans are the seed, the root, the trunk and the first people who began every human primary branch, then somehow fundamental wrongness must have taken place retroactively after the branches were formed such that fundamental wrongness developed backwards into the trunk, root and seed.
Then somehow, after that separation, the remaining portion of each primary branch developed a fundamental rightness. This is why all explanations that suggest this is true consists of many stories and falsification of facts that all contradict other fundamental truths. You now stuff like Adam and Eve were white but all humans started in Africa, yet the Garden of Eden was in Asia and so on we go in all areas of study false claims are used that contradict the rest of the information in those subject areas and across subject areas. All of this foolishness has produced many false notions maintained about Africans on the negative side and other groups on the positive side. Understand clearly that fundamental wrongness means all things negative and that we don't like. It means fundamentally evil, weak, lazy, sick, crazy, stupid and so on. Of course the opposite is what fundamental rightness means. It is this dichotomy that informs all our logic, despite us knowing that 99.9% of our genetics are exactly the same and 0.01% is the same, just differently arranged. Therefore there must be additional information that explains why Africans would be singled out as the most fundamentally wrong in the most areas while Albinos are singled out as the most fundamentally right and other groups fall somewhere in between.
What could explain that if human origins does not explain it and genetics does not explain it. Both of these actually discredit the notion. So for now, to answer the question what is fundamentally wrong with Africans, the answer must be that it's a combination of the low reasoning skills of humans and the continued daily choice of humans to misuse their free will by choosing conclusions based on false information when there is plenty of information that is well-known to disprove their conclusions.
So all of this must mean there is a fundamental defectiveness in a whole bunch of humans. Dr. Yosef Ben-Jochannan & George Simmonds (1987) | African Origins Therefore to believe there is something fundamentally wrong with Africans requires the same kind of thinking where you would take a group of humans, amputate one arm, attach a tree and then say, look at them, there's something fundamentally wrong. This is the kind of mental craziness going on in the minds of those who think there is something fundamentally wrong with Africans. You have to ignore the truth and then fabricate and attach a new truth and then blame it on someone or anything except the fact that the problem lies in your own logic.
