Prevalent genetic diseases are primarily introduced by outbreeding depression, which results from mating between unrelated or distantly related individuals, In turn, these genetic diseases tend to be concentrated in a small gene pool as a result of being isolated. There are examples this found in human cultures across the world. One of the most amazing examples of this is found in the Jewish community. Even today marriage outside the Jewish community is greatly discouraged. In essence, inbreeding makes the genetic disease more prevalent in the community (gene pool). There is no other people on Earth where this is more exemplified than within the Jewish community. The Jews have more genetic diseases than any other race in the world. Notwithstanding, there is much more to this than just simply stating it. The explanation can be realized by understanding the following. The presence of DNA/cells that originate from another individual, and are genetically distinct (racially) from the cells of the host individual, can cause certain types of autoimmune diseases. This is known as *microchimerism* and occurs from having sexual intercourse from a genetically different partner (racially different; outbreeding). The DNA/cells from a racially different sex partner has a deleterious effect to the female's own immune system, it’s homeostasis, and her mental equanimity. The DNA or RNA from sperm of a non-kindred male sexual partner influences the women's own phenotype. It also influence the traits of their subsequent offspring. This phenomena is passed on to future generations. If you have ever wondered why historically multicultural societies consistently implode into crime ridden societies, I offer this as a possible explanation warranting further investigation. Evidence shows that the male's cells/DNA from a sexual encounter has been found living in the brains of women from 38 years ago. If the male is from a similar genetic background, the DNA/cells are beneficial to the mother and baby's immune system. However, the cells/DNA from a racially different partner are in conflict with the mother’s immune system and are attacked through what is known as a cytokine storm. The body's own immune system becomes the greatest threat to the health and longevity of the female (and baby). The health consequences can be immediate and neuro-immunological diseases involving inflammation are evident through many diseases producing systemic sepsis, as defined by persistent hypotension, hyper- or hypothermia, leukocytosis or leukopenia, and often thrombocytopenia. Viral, bacterial, and fungal pulmonary infections all cause the sepsis syndrome, and these etiological agents are difficult to differentiate on clinical grounds. In some cases, persistent tissue damage without severe microbial infection in the lungs also is associated with a cytokine storm and clinical manifestations that mimic sepsis syndrome. In addition to lung infections, the cytokine storm is a consequence of severe infections in the gastrointestinal tract, urinary tract, central nervous system, skin, joint spaces, and other sites. Other diseases take hold many, many years later. The consequences are always the same. This is something that isn't publicized, but is instead censored. The studies are hidden from the public. Any mentioning of this is immediately labeled as a "myth" or racist conspiracy theory. It is a fact the children of racially mixed couples are far more apt to neuro-immunological and psychological diseases. Of any racial group, the Jews have by far the most genetic diseases, and because of this, it provides a manifested example how genetic diseases are spread to other distinct genetic groups.
