There should instead be a legal claim that doctors be allowed to punch people who even suggest that and bar them from the fertility clinic.
aside from the obvious good points already made about the "programming" of children to have a disability, i must point out the dangerous assumptions made about eugenics: about picking and choosing the features of future human beings. the dangers of this are far beyond just the historical societal irresponsibility of humankind, but also would have unknown, but most likely very negative consequences evolutionarily. so much is still unknown about the complexities of the human genome, and all studies of evolution so far indicate that random assortment of a multiplicity of alleles is the best bet for a successful species. the beautiful thing about random assortment is that new advantageous combinations cannot really be predicted, and narrowing the number by artificially over-selecting for specific "desirable" traits would probably end very badly for us. attempting to build "superhumans" by tampering with the genetic code is, and should continue to be, viewed as very unwise, and should be limited to screening for devastating illnesses. (screening is not done by tampering with the DNA, but is done by selecting embryos that do not contain the disease causing allele, which is as close as we would ever want to come to eugenics: again....the good of the child, but within the realm of good sense and science.) For good examples of negative consequences of limited gene pools, see cheetahs or purebred dogs.
