Should they be allowed? I don't think so. They should definititely adopt or foster. Most hearing couples don't know sign language or ways of communicating with a deaf child so they wouldn't adopt one, therefore I'm sure there are many deaf children sitting in children's homes who would like to be adopted. It's bizarre that they would deliberately choose to limit their childs life experience by making sure that it cannot hear.
