A person without a disability may recognize someone using a wheelchair, a guide dog or a prosthetic limb, or someone with Down syndrome, but most don’t conceptualize these people as having a shared social identity and a political status. “They” merely seem to be people to whom something unfortunate has happened, for whom something has gone terribly wrong. The one thing most people do know about being disabled is that they don’t want to be that.
