That's like saying "Lenin and Stalin did some bad stuff, but it doesn't invalidate the basic idea of Marxism" (which Marxist True Believers still assert). After seeing too many examples of it working out badly and none at all of it working well, we regard the idea as invalid. In practice, eugenics seems to move from "some genetic makeups are more fit for the current environment than others, and we should strive for those in future generations" to "some genetic makeups are better than others, and we should strive for those", to "some people are better than others, and we should strive for those", to "some people are better than others, and we should force there to not be so many of the others". There doesn't seem to be any clear point at which you can say, "No, you've gone too far", and explain to the true believer why the step they took is too far. They'll just tell you that it's logically implied by the steps that you are in agreement with. And if you disagree with this, show me historical examples of eugenics movements that stopped at reasonable places. (I probably need to qualify that with "eugenics movements that had some influence", because if you don't have enough influence to get people to accept step 1, you don't move on to step 2. And that may be begging the question on my part, because Nazi Germany may be the only historical example where the ideas got taken seriously and actually influenced much of anything.) Unrelated comment: Another danger of eugenics is exposed by my wording of the starting point: "some genetic makeups are more fit for the current environment than others..." That's clearly true. But the current environment is not necessarily the one that future generations will face; leaving them some genetic diversity (even if it creates some disadvantages) may be a net win. Remember sickle cell anemia. |
Because it doesn't. I will assert that even though I'm not a Marxist True Believer.

And that's just plain stupidity, which is exactly what I'm complaining about. It's "someone tried that before some time ago and it didn't work, therefore let's label this stupid and throw it away" kind of attitude. The real reason we're ignoring the entire idea is because communist propaganda has lost and US propaganda has won, and it has little to do with actual merits of the idea itself.
You could utter similar dismissals for fire before we mastered it, or for gasoline before we created ICEs, or for powered flight before Wright brothers. What I was asking for is an actual discussion of the idea - pointing out where the idea is wrong, and talking about how can we modify it to avoid its problems while reaping the rewards.
Which fortunately you did in the rest of your comment, so forgive me for the text above, but I really really disagree with the sentiment of your first paragraph.

I don't think we had many of such examples - the only ones we label "eugenics" happened within the last 100 years, and involved powerful people with ideology doing stupid and harmful things because doing things because of an ideology is generally stupid and harmful.

Yeah, that's a strong point I'm going to agree 100% with. Too strong adaptation to current environment means you'll be really out of luck when the environment changes.
