From a scientific standpoint eugenics works. Due to medical science and modern technology there is very little natural selection that takes place other then Ooooh big boobs. However when approaching the topic of eugenics it's important not to get caught up in ideas like a master race. Instead we should be selectively breeding to specialize our genetics much like we specialized breeds of dogs to perform different rolls and functions. The fact of the matter is there is not nearly enough genetic variation in the human race as is and this problem is only being compounded by globalization which is homogenizing human genetics even further. We should be selectively breeding to create more diversity because genetic diversity is the secret weapon that ensures the survival of a species. So the whole wipe out one ethnicity while selectively breeding another like the [url=http://www.wikipedia.org/wiki/Godwin%27s_law]-godwinslaw!-[/url]'s did is a completely false notion and only serves to shrink the diversity in the gene pool. The best way to ensure our survival as a race in the face of epidemics, overpopulation, and environmental disaster is to create this diversity through selective breeding. At the same time screening for negative genetic conditions could help eliminate them but even then one has consider things like the fact that sickle cell anemia while having negative effects also provides those afflicted with it resistance to malaria, which is a trait that provides people in equatorial regions greater survivability despite its negative impacts. I hope for the day when our species is as diverse as that of dogs. You can hate me all you want for this, it doesn't change the fact that I'm right. However I honestly don't think eugenics is even feasible in our society. So maybe eugenics isn't the answer anymore but rather our real insurance policy for the future could be genetic engineering. But we must be careful with that because like I said we are looking to create more diversity not less and so far what we've been doing with that technology has been the opposite of what the end goal is.
