>Why? Why is that the "unbiased" conclusion. You keep claiming this, but don't justify it. Also, you don't have to kill a single person. You do know that, right. You can just let people with Down Syndrome finish living out their lives.

The resources needed to support such a person have a negative effect on the parents and society in general. That is why it is unbiased.

You can let them live out their lives sure this is one way to do it. But not as effective as termination right? Monitoring people for their entire lives and controlling their behavior costs a lot of resources and is no guarantee. Slaughtering people who have down syndrome and the people who are recessive carriers guarantees categorically the defect is eliminated.

>And you'd note, I actually agreed that eugenics works. It will breed out whatever trait you want bred out. And that the reason we don't do it is because it involves ripping people's autonomy from them. And that is wrong. We should not do to others what we wouldn't allow be done to ourselves. And there's the knock on effect that we cannot agree on the clear detriments.

Yes agreed. It's "morally wrong" but your sense of morals do not align with the most logical action that benefits society and lives in aggregate.

>Why? Why is having Down Syndrome a "clear detriment" but not being black? Would you rather be black or white? Why? You could make a pretty good case that society, as a whole, would be better off if we all were one uniform skin color. So that it would be to the benefit of society if we were to breed out certain levels of melanin.

The detriment of down syndrome is clear. Resources used to support these people are expensive and they provide no benefit to society.

Your solution for a uniform color logically works. It can work from both directions actually. Slaughter all people with pale skin or slaughter all people with darker skin then everyone will have the same color skin. Logic. Both solutions will obviously have side effects that run deeper than just solving the skin color problem.

>Racism is hardly logical. It has no basis in logic. It requires the mental gymnastics you so readily accuse others of. This is not a position of disgust, this is a position of rationality. Melanin levels shouldn't determine how you are treated by others. And the solution isn't to breed out melanin, the solution is to remove the power of the people making it harder for those with increased levels of melanin.

Racism is actually behavior that is seen world wide across disparate cultures and civilizations meaning that it likely biological in origin. A biological origin indicates that it is a trait created through natural selection indicating that an aspect of racism aided human survival. We don't fully know the implications of that behavior in the modern world but historically there is some hidden logic behind that behavior that allowed the trait to be genetically universal. The complexities here make this specific topic too complex to fully analyze from a purely logical perspective, we simply don't have enough information.

We do know that skin color correlates with certain certain genetic traits. For example black people also tend to have frizzy hair. This does not preclude behavior either. Eliminating people solely based off of the color of their skin inevitably will have other effects because of these correlations.
