"the study of how to arrange reproduction within a human population to increase the occurrence of heritable characteristics regarded as desirable.

The OP was just saying that most of the non-ineffable things about love are natural selection, and that what the eugenicists wanted was already happening naturally. Nature is cruel after all.
"actively practices" is the polar opposite of natural selection.
To wit: "Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not."[1]
uhhhh, no.
