Why is it their label? Because they coined it? Why would I accept their authority as language enforcers when I don’t accept it as scientists or medical practitioners? English doesn’t have an Academy. It’s defined by its usage. If enough people use ‘bipolar’ outside any pretensions of medical diagnosis it will cease to be seen as such a term. It’s not a disease or disorder. It’s arguably not an impairment; at least for some. But it is a disability because of society’s (particularly the medical profession’s) insistence that it should be. And by leaving the label with professionals who’ll pretend it’s objective and scientific you’re denying everyone else the right to engage with it on their own terms. I’m not disabled with bipolar because of mood swings or psychotic breaks or any of the other symptoms on the checklist. I’m disabled because our society no longer tolerates how I present as being within acceptable variation. In the 80s and 90s I was enabled by my bipolar and Asperger’s because the IT industry thought some of my ‘symptoms’ valuable enough to put up with the others and hand me big pay cheques for them. It’s not labels like ‘bipolar’ or ‘autistic’ or ‘hysterical’ that are the problem. It’s the attitude people have towards what they think they represent. By leaving the labels as professional jargon you’re not only denying people with lived experience under the label the right to define it as they see it, you’re giving everyone else an out when it comes to their own attitudes towards it.
