Sanger started it but lots of world leaders including Woodrow Wilson and Adolph Hitler subscribed to the theory of purification of the races. Sanger never recommended aborting the offspring of White people, only the lower classes. Nobody at the time ever foresaw the carnage of abortion mills like Dr. Kermit Gosnell's house of horrors which specialized in late term abortion which involves turning a full term baby around in the birth canal causing a breach birth so that the head remains inside of the birth canal long enough to stab the baby in the back of the head and suck out it's brain with a frankenstein machine. Who benefits from abortion? Certainly it isn't the mother who might have mental problems similar to PTSD for the rest of her life or physical problems and cancer. It's the good old liberal man who is the biggest advocate of abortion. His future responsibilities are eliminated at the stroke of a scalpel while the woman is left to suffer the consequences. .
The first is untrue - see
Eugenics - Wikipedia
"The concept of positive eugenics to produce better human beings has existed at least since
Plato suggested
selective mating to produce a guardian class.
[12]
"The first formal negative eugenics, that is a legal provision against birth of inferior human beings, was promulgated in Western European culture by the
Christian Council of Agde in 506, which forbade marriage between cousins.
[13]
"This idea was also promoted by
William Goodell (1829–1894) who advocated the
castration and
spaying of the
insane.
[14][15]
G. K. Chesterton, an opponent of eugenics, in 1905, by photographer
Alvin Langdon Coburn
"The idea of a modern project of improving the human population through a statistical understanding of
heredity used to encourage good breeding was originally developed by
Francis Galton and, initially, was closely linked to Darwinism and his theory of
natural selection.
[16] Galton had read his half-cousin
Charles Darwin's theory of
evolution, which sought to explain the development of plant and animal species, and desired to apply it to humans. Based on his biographical studies, Galton believed that desirable human qualities were hereditary traits, though
Darwin strongly disagreed with this elaboration of his theory.
[17] In 1883, one year after Darwin's death, Galton gave his research a name:
eugenics.
[18] With the introduction of
genetics, eugenics became associated with ideology of
genetic determinism in which human character was due to genes, unaffected by education or living conditions. Many of the early geneticists were not Darwinians, and evolution theory was not needed for eugenics policies based on genetic determinism.
[16] Throughout its recent history, eugenics has remained controversial.
[19]"
(My emphasis - more detail @ the URL)
So - a half-baked idea from Darwin's half-cousin. That's where the blame for modern eugenics belongs, if anywhere.
The ascription of physical & mental issues caused by abortion to women is also untrue. The studies that purport to lead to that conclusion are themselves severely flawed.
