I personally believe there is no way for them to succeed. If they were acting in good faith the actual incease in the number of intelligent people, who would recognize cruelty when they see it, would tear it down. If they acted in bad faith, which they most definitely would, they would fill the world with these idiots.
Eugenics isn’t just done by government. The world has been limiting the reproduction of the disabled through social pressure for ages. Look at the stigma interracial relationships used to have. Examples are everywhere.
Why does everyone think eugenics only means the way the Nazis did it?
It’s a broad term people. The government is the most heavy handed way to implement it but social pressure is arguably more effective and harder to end.
That is also wrong.
