  Objections have been raised regarding the meaning of such “expressions” (see, for instance, Buchanan 1996; Nelson 2000), and the necessity of the negative message (Baily 2000; McMahan 2005), as well as the relative moral significance of the message even if it is negative and expressed (Edwards 2004). Many theorists emphasize that one can value the person with a disability, while devaluing the disability (Savulescu 2001; Glover 2006; McMahan 2005). Glover (2006), for instance, is careful to note that we should be very clear about expressing support for existing people with disabilities even as we seek prenatal testing or other genetic interventions.
