> I'm going to come out and say that this is no different than a person born without arms claiming that they're not disabled, that they're not damaged.
You might want to look at the social model of disability, because there are people who do say this. For example, wheelchair using disability rights campaigners have often said that their wheelchairs are not the problem, but the lack of ramps in shops and workplaces is what causes them to be disabled.
Of course I'm aware of it. But redefining well-known terms is a sign of groupthink, common among activist group. By pretending words mean a whole new thing, we can identify the in group, and humiliate the out group. I won't participate in that hallucination.
A disability is when you have less ability than everybody else. We can mitigate that by addressing {everything you list above}.

That's not a new concept; it's been around since the 1970s.
