this is one kind of harm caused by the abled/disabled binary when it is applied as a permanent designation to people: it erases from view the environment that enables or disables a person, and it makes invisible all of the ways that the environment is designed to enable the abled person.
it functions to other into a social class an experience that everyone is living, but some don’t recognize—the experience of needing to exist in relationship.
if we recognize that no one can live outside of relationship, and that we play both roles continuously—the carer and the cared for—then we start to recognize the moment of need without needing to label someone needy.
In designating certain people as disabled, without the embedded values of care and reciprocity at the cultural level, then the abled person gets to sidestep the role of caregiver, and there is not enough care to go around, leaving the disabled to have to negotiate for care that in a different culture would be considered a human right. I’m not just talking about healthcare. I’m talking about basic human dignity.
binaries are useful conceptual shorthand that should never be applied to people without their consent. if you can understand the value of going beyond the binary based on biological gender, and the real harm that strict adherence to that binary causes, you can understand why permanent status as a disabled person might leave some people out. What I hear when I hear “autism is always a disability” is “there are only two genders: male and female.”
