I think the word "Eugenics" by its self holds a negative societal connotation, because of its history and the evil people and evil deeds it has been connected with. I think a better term might be selective breeding. We do this in other animals, but for some reason it is taboo in humans. I don't believe a person's right to reproduce should ever be taken away, but through education, I think people could understand why breeding out certain traits would be of benefit to the species. The problem is, evolution has always decided those traits for us. If we look at the prevalence of sickle cell anemia, as an example, and the way it renders sufferers immune to malaria, the obvious conclusion is that while sickle cell anemia has its own set of problems, it has allowed many people to survive the mass-murderer that is the malaria parasite, for generations. What one person may consider an undesirable trait may be desirable to another, and what most people consider undesirable could be inherent for reasons we are not even aware of at this point, and messing with it could unleash a host of problems that we are currently unprepared to deal with. One of the pitfalls of selective breeding is that people can use it for aesthetic reasons, such as consciously preferring a certain colour of hair or skin or eyes or bone structure, or other things that are related not to a healthy future of our species, but reducing our diversity. Who gets to decide and why are questions that are hard to answer. Part of the point is that it is often frowned upon to choose not to procreate. People are called selfish and made to feel abnormal, that they are missing out on something, that they will never truly reach full adult status, and many more accusations. I choose not to have children because I am mentally ill, and have several genetic health problems that I choose not to pass on to any offspring. The man I was with until recently had also decided against having children because he has type 1 diabetes and didn't want to create a child or grandchild who would suffer the way he has. And I don't think those are ignoble decisions. Do I disagree with Eugenics? No. I believe that we could possibly do some good by not continuing to bring children into the world who will most likely suffer with genetic problems health issues that would cause them to suffer. I think that is the more responsible decision. However, I don't believe in instituting a mandatory or institutionalized way of doing it, nor do I agree that aesthetics are reasonable cause for manipulation. The question, I suppose, is where is the line drawn between what traits are acceptable and unacceptable to out-breed, and who will decide. But as I said earlier, I think people should be made aware and educated to make their own decision. Many children are unplanned to begin with, so there is already a lot of education to be done when it comes to the choice of whether or not to procreate.
