You've already been corrected on this. Plato was advocating eugenics 2000 years ago. It has been known since recorded history that human could be breed just like animals for specific traits. Breeding humans as a concept was not "taken from Darwin's theory of evolution." Breeding isn't a form of evolution anyhow, as has also been pointed out to you.
The scientific basis, however, was provided by Darwin -- and in the spirit of his times, "science" was a much more powerful argument for eugenics than had been available in the past. Hence, "Social Darwinism."

Well, you can make the claim. But if one says that "breeding" is just the imposition of a specific type of evolutionary pressure, then your "pointing out" needs to be adjusted.
