The meaning of disability can mean different things to different people, but here is the real disability definition quoted below:
Does this meaning of disability define Deaf people? Are they incapable of doing anything? There are senses that prevent you from doing something, and that is what you'd call a disability, but there's only one sense we obviously don't have. We have lost only one sense that is sound, and that's it. Yeah. Whoops, big deal.
That's why I've never thought of myself as one of the people with disabilities.
Things changed the way I viewed myself when I started a college. I was the only Deaf student in all hearing classes. I was always treated differently by my instructors and classmates. They pitied and talked down to me. I thought, "Wow, my deafness scared them that much?"
Obviously, many Deaf people have their own perceptions about disability. They hate this term because it sounds negative and it does not define them at all. They do feel deafness is a blessing for them because they do have their own culture and language. When there's a language, there's a culture.
On the other hand...
Some people, including both hearing and Deaf people, believe deafness is a disability because we have hearing assistance technology and sign language interpreter. You'll be not considered disabled if you don't need any help at all. If you can't do a job of answering the telephone, then you are considered disabled.
Before you object to the disability label, there is one question for you to consider. If you were to tell your government that you are not disabled and they would say, "You're not disabled? Okay, we'll take away your disability benefits", what would be your response to that?
