Eugenics is eugenics wherever it happens, and it is comparable.
In Germany, in 1933, the Reich Cabinet passed the "Law on Preventing Hereditarily Diseased Progeny," calling for involuntary sterilization of all those identified as bearers of hereditary disease, including deafness, blindness, 'feeblemindedness,' and even alcoholism.
It doesn't stop being eugenics just because it's voluntary in this country.
