But I would first say that deafness is obviously a disability, but then I don't think autism is a disability, yet many people do; so it is not so clearly cut as you seem to imply.
I read it in a book that the disability is being smaller in number.
Maybe humans are disabled because they cannot fly like birds.
Disabled as in lacking an ability, but the bad part is being negated by rest of society. Having your needs ignored and then being ridiculed for how they ignore you.
This should be bi-lingual country.
Then, there would not be separate deaf and hearing culture but one american culture. This would be good for especially children deaf of hearing parents and hearing children of deaf parents.
