Can it be that "White Supremacists" - another name for Nazis - are people whose brains, whose cells, have been damaged by eugenics - the result of inbreeding?
We see people full of hate striving to "purify" their nation from the genes of human beings whose skin does not appear to them to be "white".
Maybe these haters are themselves victims of inbreeding, leaving their brains vulnerable to fear and hate. Perhaps scientists might examine the brains of Nazis - Ku Klux Klan, Alt-Right, White Supremacists - even Islamic terrorists - to see if there is visible evidence of such damage. Here are some of the known consequences of eugenics.
Eugenics (/juːˈdʒɛnɪks/; from Greek εὐγενής eugenes 'well-born' from εὖ eu, 'good, well' and γένος genos, 'race, stock, kin') is a set of beliefs and practices that aims at improving the genetic quality of a human population. The exact definition of eugenics has been a matter of debate since the term was coined by Francis Galton in 1883. The concept predates this coinage, with Plato suggesting applying the principles of selective breeding to humans around 400 BCE.
Frederick Osborn's 1937 journal article "Development of a Eugenic Philosophy" framed it as a social philosophy—that is, a philosophy with implications for social order. That definition is not universally accepted. Osborn advocated for higher rates of sexual reproduction among people with desired traits (positive eugenics), or reduced rates of sexual reproduction and sterilization of people with less-desired or undesired traits (negative eugenics).
Alternatively, gene selection rather than "people selection" has recently been made possible through advances in genome editing, leading to what is sometimes called new eugenics, also known as neo-eugenics, consumer eugenics, or liberal eugenics.
While eugenic principles have been practiced as far back in world history as ancient Greece, the modern history of eugenics began in the early 20th century when a popular eugenics movement emerged in the United Kingdom and spread to many countries including the United States, Canada and most European countries. In this period, eugenic ideas were espoused across the political spectrum. Consequently, many countries adopted eugenic policies with the intent to improve the quality of their populations' genetic stock. Such programs included both "positive" measures, such as encouraging individuals deemed particularly "fit" to reproduce, and "negative" measures such as marriage prohibitions and forced sterilization of people deemed unfit for reproduction. People deemed unfit to reproduce often included people with mental or physical disabilities, people who scored in the low ranges of different IQ tests, criminals and deviants, and members of disfavored minority groups. The eugenics movement became negatively associated with Nazi Germany and the Holocaust when many of the defendants at the Nuremberg trials attempted to justify their human rights abuses by claiming there was little difference between the Nazi eugenics programs and the U.S. eugenics programs. In the decades following World War II, with the institution of human rights, many countries gradually began to abandon eugenics policies, although some Western countries, among them the United States, continued to carry out forced sterilizations.
Since the 1980s and 1990s, when new assisted reproductive technology procedures became available such as gestational surrogacy (available since 1985), preimplantation genetic diagnosis (available since 1989), and cytoplasmic transfer (first performed in 1996), fear about a possible revival of eugenics and widening of the gap between the rich and the poor has emerged.
A major criticism of eugenics policies is that, regardless of whether "negative" or "positive" policies are used, they are susceptible to abuse because the criteria of selection are determined by whichever group is in political power at the time. Furthermore, negative eugenics in particular is considered by many to be a violation of basic human rights, which include the right to reproduction. Another criticism is that eugenic policies eventually lead to a loss of genetic diversity, resulting in inbreeding depression due to lower genetic variation.
Genetic Diseases and Medical Conditions.

The term racial hygiene was used to describe an approach to eugenics in the early twentieth century, which found its most extensive implementation in Nazi Germany (Nazi eugenics). It was marked by efforts to avoid miscegenation, analogous to an animal breeder seeking purebred animals, and also to avoid social degeneration, the idea that civilization could decline by the spread of inferior characteristics.
The German eugenicist Alfred Ploetz introduced the term Rassenhygiene in his "Racial hygiene basics" (Grundlinien einer Rassenhygiene) in 1895. He discussed the importance of avoiding "counterselective forces" such as war, inbreeding, free healthcare for the poor, alcohol and venereal disease. In its earliest incarnation it was concerned more with the declining birthrate of the German state and the increasing number of mentally-ill and disabled people in state-run institutions (and their costs to the state) than with the "Jewish question" and "degeneration of the Nordic race" (Entnordung) which would come to dominate its philosophy in Germany from the 1920s to the Second World War.

In Nazi propaganda, the term "race" was often interchangeably used to mean the "Aryan" or Germanic "Übermenschen", which was said to represent an ideal and pure master race that was biologically superior to all other races. In the 1930s, under eugenicist Ernst Rüdin, National Socialist ideology embraced this latter use of "racial hygiene", which demanded Aryan racial purity and condemned miscegenation. That belief in the importance of German racial purity often served as the theoretical backbone of Nazi policies of racial superiority and later genocide. The policies began in 1935, when the National Socialists enacted the Nuremberg Laws, which legislated racial purity by forbidding sexual relations and marriages between Aryans and non-Aryans as Rassenschande (racial shame).
Racial hygienists played key roles in the Holocaust, the German National Socialist effort to purge Europe of Jews, Romani people, Poles, Serbs (along with majority of other Slavs), Blacks, mixed race people, the physically, and intellectually disabled people. In the Aktion T4 program, Hitler ordered the execution of mentally-ill patients by euthanasia under the cover of deaths from strokes and illnesses. The methods and equipment that had been used in the murder of thousands of mentally ill were then transferred to concentration camps because the materials and resources needed to efficiently kill incredibly-large numbers of people existed and had been proven successful. The nurses and the staff who had assisted and performed the killings were then moved along with the gas chambers to the concentration camps, which were being built in order to be able to replicate the mass murders repeatedly.

The doctors who executed horrific experiments on the prisoners in concentration camps specialised in racial hygiene and used the supposed science to back their medical experiments. Some of the experiments were used for general medical research, for example by injecting prisoners with known diseases to test vaccines or possible cures. Other experiments were used to further the Germans' war strategy by putting prisoners in vacuum chambers to see what could happen to pilots' bodies if they were ejected at a high altitude or immerse human prisoners in ice water to see how long they would survive and what materials could be used to prolong life to be able to make effective coats or suits for German pilots who get shot down in the English Channel. The precursors of they notion were earlier performing medical experiments on African prisoners of war in concentration camps in Namibia during the Herero and Namaqua Genocide.
A key part of National Socialism was the concept of racial hygiene and the field was elevated to the primary philosophy of the German medical community, first by activist physicians within the medical profession, particularly amongst psychiatrists. That was later codified and institutionalized during and after the Nazis' rise to power in 1933, during the process of Gleichschaltung (literally, "coordination" or "unification"), which streamlined the medical and mental hygiene (mental health) profession into a rigid hierarchy with National Socialist-sanctioned leadership at the top.
The blueprint for Nazism's attitude toward other races was written by Erwin Baur, Fritz Lenz and Eugen Fischer and published under the title Human Heredity Theory and Racial Hygiene (1936).
Inbreeding and Genetic Disorder
Genetic Mutations Caused By Inbreeding
People from all ethnic backgrounds can give birth to children who have albinism. Those who live with the condition have an absence of melanin in their skin, hair, and eyes. As a result, their hair can be pale blond to white, their eyes are usually a fair blue, and they often have vision problems. Why does it happen? Well, one possibility is inbreeding. Because albinism is an autosomal recessive condition, people who are related and intermarry or mate are more inclined to give birth to children with the disease.
During the days of traveling circuses, people with microcephaly were often put on display as freaks, just like the famous "Schlitzie the Pinhead" was. So no, the condition is not at all new to the medical world, although it has been making headlines lately as the Zika virus has been giving pregnant women quite a scare in the last few years. When women are infected by the virus while with child, their babies become susceptible to being affected by the disease. The head of the child would then become under-grown, the brain not forming fully either.
3. Fused Limbs
Movies and television shows like to depict children of incest as mongrels with eleven fingers and disfigured faces, but in reality, those are more uncommon traits. Surprisingly, however, children born with fused limbs are common. In such cases, fingers or toes are fully grown, but the skin and flesh around one or two of them are linked together. The condition is called polydactylism and can make parts of the body webbed or like one strange, alien-like unit.
4. The Habsburg Jaw
Having a long jaw doesn't necessarily mean that you come from a family of inbreds, but it does seem to be a trait that the House of Habsburg couldn't avoid. The noble family rose to power during the 1400s and reigned for 300 years, and like many royal families, they didn't want to intermingle their bloodline with peasants. For that purpose, they married and had children with relatives in order to keep the wealth within the family. Unfortunately, as generations went on, physical attributes started to change, including a long, protruding lower jaw with a highly noticeable under bite.
5. Cleft Palate
A cleft palate is said to occur when the roof of the mouth improperly forms, thus causing the sinus passage to remain open. It's easy to spot people with this condition because it looks as if they have an ill-formed upper lip that lifts into their noses. And while it may look as if it's strictly a cosmetic issue, people with cleft palates have difficulty breathing, eating, swallowing, and sometimes speaking. This condition is said to form in the womb, and in places such as India or Kenya, where inbreeding runs rampant in small tribes, many babies are born with cleft palates.
6. Elongated Skull
Once thought to have come from the artistic imaginations of ancient Egyptians, elongated heads weren't actually exaggerations. In fact, researchers now claim that the statues and busts showing elongated heads are accurate representations of the way the Egyptian royalty actually looked — their skulls developing that way as a result of years upon years of inbreeding. Ancient Egyptian royal bloodlines were riddled with incest as marriages between siblings and cousins were common.
People with dwarfism don't necessarily come from long lines of inbreeding, but when tribes and small villages where inbreeding was common were studied, there was a higher rate of little people being born within those groups. In fact, the Ellis-van Creveld syndrome — the more scientific name for dwarfism — has been found among people in isolated populations, such as the Amish who are settled in Lancaster, Pennsylvania. In the 1700s, children with dwarfism born into this community, often came out of their mother's womb with teeth, cleft palates, misshapen wrists, heart defects, fused limbs, and missing fingernails.
