And anyone who watched this wk's episode of PBS's American Experience on this country's early 20th C Eugenics movement - which was flourishing mightily until the horrors of Naziism (Hitler cited American racial-purity theories in Mein Kampf) shamed it out of existence - know how pervasive the impulse to pursue a superrace can become.. They showed how easy it could be, a century ago, for a person to be suckered in by the notion that, the whiter (Nordic=perfect, so to speak) people got, the more healthy and prosperous they became, but i had no idea that it had gone to the extent of sterilizing 60,000 Americans for mental/moral unfitness. The sterilization movement was in fact expanding - so much so that the Supreme Court decision which legalized "sterilizing the unfit" was written by Oliver Wendell Holmes and Margaret Sanger attached herself to the movement to advance her cause of reproductive rights - when WWII began.
