I'm 100% pro-eugenics-like-stuff, and 100% anti-actual-implementations-of-eugenics.
Really, classic Eugenics is the equivalent of saying "Lets create a chihuahua by neutering every Great Bernard we can find!"
It's... beyond stupid. It's worse than stupid, because you know it has to be willful stupidity, a lie to themselves, because of how stupid it is.
Regardless, I definitely support guided evolution of humans, but any attempt at guidance at a species-level is both highly immoral and laughably doomed to failure, in addition to being... poorly thought out. No one can be optimized for everything, after all.
Rather, work creating subpopulations specializing in certain things (both genetically and culturally - those things can not be taken separately, they reinforce each other!) would, I think, be highly beneficial, and hell, this is the sort of thing that happens anyways, we might as well try to put it towards good ends.
And as long as whatever organization pushes for it doesn't violate things like consent or has immoral end-goals in mind, I don't see how it would be even slightly immoral.
But yeah, that's not exactly Eugenics, just selective breeding. So anti-eugenics, pro-selective-breeding.
