People hate and fear eugenics because the Nazis liked it, I'm told. Of course, the Nazis liked working out and being fit, but we don't hate and fear physical fitness. I expect they liked many other things we also like, as well as some things we rightly hate. Selectivity is the issue.
I don't entirely understand why having children who are smarter, healthier, more attractive and longer-lived is such a bad deal. All of that sounds good to me, and I suppose it sounds good to others if we can keep the scare word "eugenics" out of it.
As DNA code testing becomes widespread, we may back into something that looks and feels a lot like ... eugenics. See this article in The Telegraph (U.K.) for more.
