Science was defeated eugenics with the correct scientific and religious basis, although there were some supporters so far.

What is known as eugenics began as science fiction in 1863, when Sir Francis Galton, Charles Darwin's cousin, assumed "the author of the theory of evolution that traces the origin of man back to the ape. It is a very famous theory that has become much controversial until now." Sir Galton assumed that if talented people marry Only from other talented people would the result be better offspring, and at the turn of the last century, with the presence of a large English community in America, Galton's ideas were imported into the United States just as Gregor Mendel's principles of heredity were rediscovered.American eugenics zealously assumed that it had no shadow of truth in a heavenly book that the same Mendelian concepts that determine the color and size of peas, corn, and cattle also govern the social and intellectual personality of the human being.

In the last century, a severe ethnic conflict was raging in America from the immigration disturbances in the early twentieth century. The elites and the so-called "progressives" showed their burning racial fears and class prejudices with their desire to make a better world for them only, so they revived Galton's theory of eugenics and turned it into an oppressive and racist ideology. From that is to increase the numbers of that elite class on the basis that they are the only ones in America to control society economically, socially, and biologically, and the other groups are less and have no influence at all.
The superior types sought by the eugenics movement were not limited only to tall, strong, talented, and intelligent people of the North with blue eyes, white skin, and blond hair. Migrant Asian workers, Indians, Latins, Eastern Europeans, Jews, dark-haired hill folk, the poor, the infirm, and anyone genuinely classified outside the novel genetic strains developed by American ethnologists.
Eugenics proved to be a racist pseudoscience designed to eliminate all humans deemed "unfit" while preserving only those who conformed to the stereotype in the Nordic countries. That philosophy was enshrined as a national policy through compulsory sterilization and apartheid laws as well as marriage restrictions, which were enacted in twenty-seven states. In 1909, California became the third state to adopt such laws. In the end, eugenics practitioners forcibly sterilized nearly 60,000 Americans, banned thousands of marriages, forcibly isolated thousands in "colonies", and persecuted odd countless numbers before World War II when nearly half of the forced sterilizations were performed in California.
California was the epicenter of the American eugenics movement. During the early decades of the twentieth century, California eugenics scientists included powerful but little-known race scientists, such as Army venereologist Dr. Paul Bobino, citrus mogul, and Polytechnic benefactor Paul Gosney, Sacramento banker Charles M. Goethe, as well as members from California. State Board of Charities and Corrections and the University of California Board of Governors.

Modern eugenics would have been extremely bizarre had it not been for the massive funding by charities, specifically the Carnegie Foundation, the Rockefeller Foundation, and the Harriman railroad fortune. They were all allied with some of America's most respected scholars hailing from prestigious universities such as Stamford, Yale, Harvard, and Princeton. These academics embraced race theory and ethnology, then falsified and misrepresented the data to serve the racist goals of eugenics.
In 1904, the Carnegie Foundation established a laboratory complex in Cold Spring Harbor on Long Island that stored millions of index cards on average Americans as researchers carefully planned to remove families, bloodlines, and entire peoples. From Cold Spring Harbor, eugenics advocates have raged in the U.S. legislatures, as well as the nation's social service agencies and associations.

In the end, one can ask without question whether this pseudo-racial science called Tahseen succeeded in the acquisition of the white race in America in theory. This happened for a while, but with the nature of the increase in reproductive capacity in blacks, Latins, and others, it is expected that white Americans will become a minority in 2040 according to the latest reports because they assumed The color of the skin is related to intelligence, strength, ability, and eligibility to lead without others, and they dyed this with a religious color without a single correct basis from any divine book because all the divine religions did not talk about the formal features of the pious, righteous, and attentive people who are useful but talked about their mental, behavioral and psychological traits.
