Creating babies with disabilities

This article was really interesting. It is about a bioethical debate whether parents should be allowed to screen babies for disabilities ... as in to choose babies with disabilities. The question focuses on in-vitro babies which usually get a preimplantation genetic diagnosis, to throw away embryos with disabilities. Parents who are deaf or dwarfs for example wish to have children who are "like them."
