Eugenics is pseudoscience... basically technobabble. It is simply taking a few concepts from the discipline of genetics, and apply it in an incomplete form to something else, with added bias.
There is really no "superior genes". Just read up a bit on sickle-cell disease and you'll see.
It's all so relative to the environment. What is desireable now may not be so down the line, so saying that one trait of humanity is better than another is simply misinformed judgment. Eugenics takes it a step further by acting on the misinformation, and so becomes reckless prejudice.
And if you include the traits of only a certain race or genetic stock into question... well...
The old Eugenics was based on Morphology, which was inaccurate. Genetics did not exist back then. The modern Eugenics is nothing else but practical Genetics, and Genetics is a very accurate science.
Which means, that to condemn Eugenics nowadays you would have to say something like "the human phenotype is 100% independent of its genotype", which is obviously a contradictio in adjecto.
But I see where you are going with your "sickle-cell disease". You claim that an organism with a crazy mutation is as viable as a healthy organism, because in a crazy environment the crazy mutation may become an advantage? But then you say it's dependent on the environment? It is indeed, and in an environment where Malaria can be prevented and healed, the sickle cell trait is redundant, and the sickle cell disease clearly disadvantageous.
And as Nekohime already mentioned, Eugenics is SUCCESSFULLY practiced in Humans, and prevented many diseases, even exterminating some. So obviously you just have no idea whatsoever what you are talking about, calling Eugenics a pseudoscience. You are probably suffering from sickle-cell DISEASE and you are not gutsy enough to admit that it's a disadvantage.

In "Beyond this Horizon" by Heinlein the society described practices a form of eugenics that I can get behind. Basically, you still choose who your partner will be, but you can pick and choose the characteristics of your child within the set of genes you both have. Want the dad's blue eyes and the mom's musical talent, but not the mom's near-sightedness and the dad's allergies? You can do that. Each couple gets a child that is genetically theirs, but is tailored according to what the parents want. Since the state or any external party is not choosing a certain set of traits for everyone, and the genes still come from different people, this method would still allow for a reasonably high amount of genetic diversity.
We already practice a form of this type of eugenics right now--there is genetic counseling, where people can find out if they are carriers for certain diseases (e.g. sickle-cell anemia, hemophilia), and there is also fetal DNA testing for stuff like Down syndrome. I'm all for improving this to the point where we can actually choose specific traits, but the choice of who to marry and what traits to choose for children should always remain in the individuals' hands. This, of course, assumes that the parents know best and would choose to use this technology for the benefit of the next generation instead of exploiting it, but it's better than having the choices forced upon the parents.
This is why you women should stop reading novels. You can't just pick and choose certain physical and mental traits from your parents. You could only observe and replicate them via genetic engineering.
Read up on meiosis - this is how genes are inherited. You can't "improve this to the point where we can actually choose specific traits", because those are TWO ENTIRELY DIFFERENT THINGS!
If you were "to pick and choose traits", you could replicate any DNA-sequence, not only the one of your parents. Meaning if one of your Grandmothers had a sloping forehead, and your other Grandmother had a straight forehead, you could have a convex forehead as well as a sloping or a straight one. This is genetic engineering, you just manipulate the DNA as you wish. You could make your children look like Brad Pitt. This is the danger of genetic engineering; people are directly manipulating the genes. If it becomes a trend it could not only cause abnormal mutations, but catastrophic epidemics that could exterminate all of mankind within a shortest period of time. And viruses and bacteria are impossible to predict, and will always find a way to "crack" the target organism.
So the only thing that is to choose and that should be chosen wisely is the partner with all of his genes, because it is theoretically impossible to "choose" certain genes.
YES to Eugenics. YES to partner selection according to genes!
NO to Genetic Engineering. NO to botching around in the human genome!
