Did you know, that many of the German ideas regarding inferior people and how to deal with them actually was based on some of our work?
The Germans didn’t do much regards eugenics prior to the Nazis (they were far behind), and when they took power they actually looked towards the US where you had active eugenics programs. Also something we would rather bury in the annals of time.
On one of my trips (I love to travel) I stopped and had to snoop around where much of that was done and what the Nazis actually based some of their program on: https://en.wikipedia.org/wiki/Virginia_State_Colony_for_Epileptics_and_Feebleminded
Some of the buildings still stand to this day, I was there maybe 6 months ago.
LOL...of course I knew that and eugenics was also a VERY big thing with the lefty/progressive and Suffragettes in the UK; in late Victorian/Edwardian times!
