Over the years, I have noticed a troubling conflict in the way people speak about disorders and disabilities which are different from their own.
"You don't have tics, you have Munchausen's"
"You don't have DID, you have schizophrenia"
"You're not chronically ill, you're just a narcissist"
This sentiment that you cannot have xyz disorder, are lying or "insane", and must truly have this other disorder instead.
It is as if there are the Good Disorders; those which are Morally Correct to have; those which you are subjected to; those which make your life harder, and the Bad Disorders; those which are Morally Wrong to have; those which you deserve to have; those which make other peoples' lives harder. And so, there is this idea that those with the Bad Disorders attempt to trick others into believing they actually have the Good Disorders, and that this must be called out and these people shamed and exorcised so as to not taint the purity of those with the Good Disorders.
It is what is behind this common demand of "You must acknowledge you have The Bad Disorder and seperate yourself from those of us with The Good Disorder, or else you will further our oppression, harm us, steal our resources, and spread lies about our disorder."
And then I realized, it is that a lot of people believe that Good People have Good Disorders and Bad People have Bad Disorders.
Good People have disorders such as PTSD, anxiety, depression; Bad People have disorders such as personality disorders, bipolar, schizophrenia.
And so, Bad People cannot have Good Disorders. I feel that this also ties into ideas of what "victims of disability/abuse" look like, and the idea of the Good Victim; this idea that in order to be truly victimized, you must be entirely and wholly pure behaviorally, emotionally, physically, racially, and sexually, or else you are considered to be deceitful and deserving of abuse and disability. Those who are "truly" victims are those who are deemed to fully reject their abuse and disability, and who are also deemed to be wholly pure and good.
For those who are held up as Good Victims [of disability/abuse], it is said that they deserve support, justice, and healing. For those who are decided to be Bad Victims [of disability/abuse], it is said they deserve isolation, institionalization, violence, and perhaps even death.
Even within communities for specific disorders, there are the Good Symptoms and the Bad Symptoms, and it is a common sentiment that those with the Bad Symptoms must not truly have the disorder; to imply otherwise would risk the purity of the disorder (or, if it is a "Bad Disorder", it damages the possibility of the disorder someday moving into a Good Disorder status).
This entire structure relies on deeply ingrained ableist ideals and concepts of morality, purity, and dis/ability. It keeps us divided from each other and damages attempts at community.
Dismantling ableism requires supporting each other; when we perpetuate the idea that other disabled people are lying about their disability, that they are not who or what they claim to be, and that they require immediate curative interventions in order to not harm others, we reinforce ableist ideas and stereotypes about disabled people within our communities.
