There was actually a medical journal, “Journal of Eugenics” published in the early 1900s. One university I attended had the entire publication run of that journal in the library. I remember picking one up and thumbing through it; unfortunately, I do not remember what I read there.
Eugenics was considered the wave of the future, until the Nazis came along. Its adherents then changed its name, but the belief system is still with us.
There was a series of letters exchanged, between a contributor to that journal and the Nazi regime. I forget the names. But, there is a clear indication that the eugenics movement in the United States was regarded as a model by the Nazis, who implemented it themselves and then some, eventually to a monstrous scale of killing outright. That’s why eugenics is now a dirty word among those who still advocate it, and why the name “Planned Parenthood” came into being. Look into the name of that organization before.
