This is one of the most horrific things I have ever seen: a Nazi "baby farm", the preferred method of raising the next generation of Superbeings to serve the Third Reich.
So deluded were they that they seemed to believe that rough-handling infants, slinging them around by the feet and massing them together like a product was the best and most efficient way of producing a healthy population of emotionless thugs for the Third Reich. They look like they are all the same age and size, reminding me most horribly of the rigid uniformity in Leni Reifenstahl's Triumph of the Will They resemble plucked chickens who have somehow survived processing and evisceration. Most of these would either have been kidnapped from invaded countries (if their Aryan blood was deemed to be pure) or bred from blonde-haired maidens and officers in the elite corps of the SS.
How could this happen? we ask over and over again. It's the same thing that happens in cults. People surrender their will. So much for triumph. Babies en masse, surrendered to the Cause. Brains facing forward, all without a single thought.
