Sterilization of criminals was a FANTASTIC practice.
Sterilization of white criminals, black criminals, I don't care, it was a FANTASTIC practice.
I think even under Hitler, something like only 1% of the targeted groups were killed. I think even the Wikipedia death rate of Jews LIVING in Germany was 25.1% - and that is the HIGH estimate according to Wikipedia! The table is here:
https://en.wikipedia.org/wiki/World_War_II_casualties#Jewish_deathsSounds like Hitler sure was good at being an efficient genocidal maniac.

Or maybe there is a lot more to the "official" Hollywood version of events. You would think that if Hitler was so keen on killing every Jew in the world, that he wouldn't have allowed 75% of the Jews living in his dictatorship to survive.
Not that Jews were targeted by Hitler due to being too dumb - just the opposite, Hitler thought Jews were the greatest evolutionary competition to Aryans.
But in any case, even under a dictatorship, eugenics is virtually impossible. What we should do is stop encouraging DYSGENICS - we are literally encouraging and incentivizing the dumbest people into reproducing. It's awful. Universities are promoting this, and fast driving the value of having an accredited degree into the ground as a result of promoting this level of leftist stupidity.
