I was trying to find a succinct way to express that I had no disabilities rather than just that I can see. I'm aware my phrasing was awkward but hope people would realise there is no offence intended.
The politically correct term is "temporarily abled." This sounds goofy at first, until we realize that if we live long enough, nearly all of us lose our abilities in one way or another.
It doesn't matter what you call it - nothing is going to change the reality. You might as well use the first word that was coined for it and stop. Every new word you find will eventually have the same emotional significance, since the underlying reality isn't going to change.
And calling something by how you're not going to have it is ridiculous - yes, please walk into my charred pieces of wood, while I search for my soon to be lost keys and give you a ride in the crushed metal.
The "euphemism treadmill" is interesting, but the goal in changing terminology isn't necessarily to escape previous negative connotations. It usually better reflects our current understanding of a particular disability or state. Saying that it doesn't change the reality is pretty ignorant; many people overcome physical disabilities, only to be looked down upon by society.
For example, "retard" is overwhelmingly negative. Saying someone has a learning disability doesn't magically make them learn better, but it does:
A) treat them as a person. Imagine if we had a particular term for a person with cancer. They're not a person now, they're a "cancee", or whatever the term is. This is degrading, you're defining them in terms of their illness. The same is true of mental illnesses and physical disabilities.
B) affect reality by changing the social situation. Treating someone with a disability with respect and referring to them in the way they prefer doesn't fix all their problems, but it is a contribution you can make to helping them. This is really true of all people; you might not be able to fix everyone's problems, but you should still be nice to them.
I agree that the currently able label is a stretch, partially because it's about labeling yourself. If you don't want to be referred to as currently able, that's your choice, and I don't think it negatively impacts other people.
Edit: I meant to add that a good counter example for the treadmill is reclamation: see dyke marches, use of the word "nigger" in black culture. There aren't a lot of terms that have come full circle in modern culture, but there also aren't many iterations on the treadmill so far
Regarding the "euphemism treadmill": sometimes it is necessary to coin a new euphemism. For example, if the common usage of a word is different from its original meaning. "Homosexual" was the name of a psychological disorder, "moron", "retard", and "idiot" were all clinical definitions of mental handicap.
Times change, words continuously change meaning. Use the words that your audience understands, not the ones that your audience understood last week or one hundred years ago.
I think we agree that the euphemism treadmill(ET) exists, and that (ET) means that our words constantly change meaning.
Your original post used it as a reason not to coin a new word:
>>>It doesn't matter what you call it - nothing is going to change the reality. You might as well use the first word that was coined for it and stop.
I am saying that the (ET) is precisely the reason to coin a new word. Otherwise, your audience will not understand what you are talking about.
If you speak a language your audience doesn't understand, your audience will not understand your language. This applies to all languages: french, english, perl, python, and the euphemism treadmill.
When in Rome, do as the Romans do, including speaking the languages they understand if you would like them to understand your speech.
But whether I say "cripple" or "disabled person" or whatever the current euphemism du jour is, surely any audience understands what I mean equally well.
I've never heard this term, so far it looks like it has pretty niche use. In my experience I would just describe myself as "someone without a disability", "a person who does not have a disability".
