The problem with eugenics is the discrimination, the suffering, the brutality, and the cruelty involved - and it always was.
The problem was never with the end goal of improving the genetic condition of the population, the problem was their means. They forcibly sterilized people, & killed disabled people just for being disabled. That's not OK at all.
Elective genetic modification allows total individual choice/freedom & isn't cruel. There's no ethical issue.
@Smersh @Nicho Sure, and that was a mistake.
... because we can achieve the same goals with voluntary, elective, optional (and subsidized, so everyone who wants it can afford it) genetic engineering - no suffering, no discrimination, and no totalitarian interference required!
