Yep, I'm disabled. This wasn't at all hard to accept, and I don't see why people treat it like its hard to accept. I'm not worse because I'm disabled, I'm just disabled. I'm just me.
To me "disabled" doesn't have an innate negative emotion associated like it does for some people.
As for "disabled person" vs "person with a disability", I don't care much. If people actively are using one to look down on me, I'll tend to prefer the other in that situation, but not strongly. If someone is using person-first language because they think a disability makes me lesser, and we need to focus on the fact that am a person first, then I want to get the point across that no I don't need person first language, because of course I'm a person, just like a female is a person and a mother is a person and an American is a person. It's not negative that I'm disabled.
For "differently-abled". I don't like that term. It feels awkward and strange to use. It feels like its making all the wrong points.
Everyone is different. Everyone has different abilities. We shouldn't expect any two people to have the same abilities, whether they're NT or autistic.
What matters with the disability, is that some of our abilities /don't fit in society/. Everyone has different strengths and weaknesses, but the things that a disabled person can't do are expected by society and cause problems at a different level than the level of everyone just being different - not everyone can run or carry 30 boxes. This causes problems at times, yet its not a disability because that's not needed by society, yet its still just as "differently-abled" with how people talk about that word.
It makes me feel like people want to use the social model of disability and deny it at the same time. It doesn't make sense. Either you're disabled or not, of course you're differently-abled, everyone is.
