Original sentence: Although eugenics was widely supported by thinkers worldwide since its inception, the invocation of eugenics by the government of Nazi Germany as a justification for its racial policies caused the philosophy to become newly controversial after World War II.Eugenicists seek to improve humanity from a genetic and evolutionary perspective and hope to reduce human suffering by doing so.Eugenics (from the Greek ευγενής, for "well-born") is a social philosophy (sometimes labeled a "science", a "movement", or, after World War II, a "pseudoscience") which advocates to improve human hereditary qualities.Proposed means of doing so have included but are not limited to selective breeding, encouragement and discouragement of certain types of reproductive practices, and genetic engineering.The idea of eugenics was first formulated by Sir Francis Galton in 1865 (though the term was not coined until 1883), and eventually came to encompass the idea of using social policies which fell into the categories of "positive" eugenics (encouraging  the "most fit" to reproduce more often) and "negative" eugenics (discouraging or preventing the "less fit" from reproducing)
Edited sentence: After World War II, however, the invocation of eugenics by the government of Nazi Germany as a justification for its racial policies caused the philosophy to become almost universally reviled.Eugenics (from the Greek ευγενής, for "well-born") is a social philosophy (sometimes labeled a "science" or a "pseudoscience") which advocates to improve hereditary qualities by social control of human reproduction.The idea was first formulated by Sir Francis Galton in 1865 (though the term was not coined until 1883), and eventually came to encompass the idea of using social policies which fell into the categories of "positive" eugenics (encouraging  the "most fit" to reproduce more often) and "negative" eugenics (discouraging or preventing the "less fit" from reproducing)
