I did see some comments by OP, whether feigning ignorance or truly unaware, I wanted to make a comment that was unambiguous and very clear.
It seemed OP was unhappy with some of the other responses or felt like it wasn’t entirely answered so this way hopefully there is no confusion that the concept they were asking about just does not exist. If it was ignorance, hopefully they learned and move on. If not, well that’s a choice they made and there’s nothing us internet people can do beside answer honestly and condemn poor viewpoints like eugenics.
