 Recently, Elizabeth Barnes has sought to challenge this perceived asymmetry between measures to prevent or correct disabilities and other significant characteristics. She attributes much of the objection to changing sex or gender to moral considerations equally applicable to “correcting” disability: 1) they would violate the individual’s right to control her own body unless consented to; if consented to, they would be permissible elective procedures (as would, Barnes maintains, procedures to create disabilities); and 2) such procedures generally involve considerable loss and transition costs—but so do procedures to correct disabilities, as many “cure” narratives attest. For preventative measures not involving bodily modification, loss, or transition costs, Barnes argues that the claimed difference between preventing disabilities and preventing less favored races or sexual orientations is simply question-begging—no good reason has been given to accept the former and reject the latter, merely the “negative-difference” view the intuition is supposed to support.
