In response to your post. Eugenics was sadly a think in the pre-WW2 post-WW1 United States -- Specifically California! PBS Documentaries on Amazon Prime had a documentary I watched last year should be easy to find. I couldn't watch it all it made me sick to see how they treated disabled children. The Nazi's took it to another level. Which is why I'm glad my grandfather killed many and came home so I was able to spend half my life knowing him. <3
