I'm here to explore the ideas around this, not trash nor proselytize any particular idea for the sake of it. You won't get very far by starting with comparing deafness to having been raped or having your leg blown off. Rape survivors are not a distinct cultural group.
Take deafness and ability entirely out of the equation for now.
People who speak sign language as a native language are a distinct cultural group with a long and separate heritage from the hearing world. For example, American Sign Language is related to French Sign Language and the speakers of each can understand each other somewhat. While British Sign Language is totally different and American and British deaf people can't even easily speak to each other in sign, only in writing. There's a whole cultural world there, as vibrant and functional as hearing ones.
They get along fairly well. People born deaf and raised in a deaf community generally have better outcomes socially and economically compared to deaf people raised in isolation in hearing culture. Yes, they cannot hear, but they don't feel they're missing anything and, functionally speaking, they'd survive on their own just fine without hearing.
I was born quite hard of hearing, and I am going deaf as I get older. I was raised hearing. Bitterly ironically, I'm musically talented and it is one of my great pleasures. I am also linguistically talented, particularly with phonetics. (Taught myself in my teens to improve my speech and it became a fascination.) And yet I am losing the capacity to sense those things.
Trust me. I get it. I get it very well. The deaf have no idea what they're missing.
And yet Deaf culture is a precious thing that also deserves to exist.
It is an impasse and a seeming paradox and I don't have an answer. Raise every child hearing and allowing sign and the culture to die out is undesirable just as people who could hear music and speech being unable to hear them is.
