Eugenic ethics: https://www.csustan.edu/history/hitlers-ethic

A quote from feynman: "Science is the belief in the ignorance of experts"

Also eugenics is literally the belief that the genome can and should be improved via intervention beyond mate selection. Which you already hold. If you are incapable of seeing the connection between "we should be allowed to edit the genome" -> "we should improve the human genome" then i doubt you are engaging on good faith and im concerned about your elementary mental capacity
