One of the problem is the constant use of the word "eugenics". Whatever will emerge as a result of current and future biological research, is not going to resemble old school eugenics from times when even the DNA wasn't understood. You have a lot of results that are used in practice already today. Embryos in IVF are genetically screened to weed out serious issues, and so are often developing foetuses in natural pregnancies. Certain countries have genetic counseling to reduce frequency of locally important diseases such as Tay-Sachs. Aren't these methods of preventing human suffering valuable?
