Okay. Fuck it, I'm going to weigh in as an actual disabled person.
DISABILITY ACTIVISM ISN'T TRYING TO BAN STAIRS FOREVER. WE JUST WANT YOU TO ADD AN ELEVATOR.
Accessibility is not a monolith. Okay? There is not some universally accessible way of existence where if you achieve it, you've finally found nirvana or some shit. Maybe the dyslexia-friendly extension that changes it up for some people will cause eyestrain for others. The descriptive audio that makes a movie friendly to blind people might detract from the experience of the Deaf person who's trying to watch the movie.
Disabled people are not immune to infighting and clashing access needs. It happens all the time! And all we can really do about it is try not to take things personally, and create multiple options to try and accommodate as many people as we can.
Being disabled doesn't mean that you want to bring the world down to your level to make things "equal." I can't run, but I'll still cheer for anyone doing marathon training. Frankly, if everyone in the world was magically made as disabled as me, that would be kind of miserable! Like, I'm depressed and tired and my joints don't work. I'm not going to wish that on others.
But what I do want is options for me to be included. I won't run a marathon, but I'd like supportive seating in the crowd so I can watch. And I don't want to be held to the same standards as the racers, either.
So, circling back to the original topic: sometimes, there will be a need for plain language. Yes, this is the official term. To my knowledge, it comes up largely in medical and legal contexts, and is defined as language that is simple and easy to understand. It benefits those with low literacy or cognitive disabilities, and is easier to translate into other languages.
Oh my god, for fuck's sake, this is an accessibility option, not an arbitrary limitation we should impose on every single piece of writing ever. Can you have some sympathy for us pedantic autistics whose inner selves are best expressed via pretentious sesquipedalian loquaciousness? Can you sit with me and try to understand neuroplasticity and the idea that improving your literacy will improve your life? Do you have any idea how much benefit public libraries are adding to our society? Can you think about who would benefit from lowering public literacy rates? The artistic destruction as a result of simplifying language?
Maybe I'm biased, but if you read your history, a lot of people don't actually care about disabled populations. Look up the capitol crawl, the ugly laws, the dark side of freak shows. Disabled bodyminds are exploited for perverse fascination and reduced to the margins of society to quietly die. Every inch of ground we have in terms of rights, we have had to fight for tooth and nail. I spend time with my loving extended family and have to explain very basic theory such as "medical abuse is a thing that exists" or "I don't want a cure" while asking myself how many more microaggressions I can endure. I'm not going to lie, it is rough. And I'm on the more privileged side of things, intersectionally speaking.
So when I hear people saying that something like this is "for the benefit of disabled people," it's pretty damning that they don't seem to have asked a single disabled person for their opinion before spouting such deranged nonsense. Disability, disabled minds, are just props to further their agenda and make themselves appear more charitable. And personally I think I deserve to run these bitches over with my rollator.
