It is serious. I think it's an argument that has enough internal sense and structure that it can't just be called a stupid argument and tossed out.
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.
Being deaf is an inherently negative aspect. You either have the ability to hear, or you do not. If you do not, it is a dis-ability. No one wants to lose an ability to do something.
Someone who lives an extensive period of time without an ability may have learned how to live without this ability. They learn to cope and affirm their life with its faults in their current state. Offering the ability they lost and have learned to live without may be declined because of the affirmation of their life as it is. It could be declined because the transition is uncomfortable as well. Either way, being deaf is still negative, they've just psychologically coped well.
If you had the choice, would you choose that your child be deaf or not? That you be deaf or not? If one isn't deaf, would they choose to become deaf or not? This entire argument results from academic nonsense that anyone outside that context can see through.
Regarding culture, culture is defined as "the customs, arts, social institutions, and achievements of a particular nation, people, or other social group.". A social group of veterans (injured or not) absolutely can be considered equivalent as your usage. Preventing war is a cultural genocide if you consider it that way. You're saying that a culture which arises from suffering, injury, evil and so on deserves preservation by refusing to prevent the evil that causes them. Alcoholics Anonymous has a culture, Gamblers Anonymous, etc.
Yes, it is academic nonsense based on semantics. It doesn't matter if they don't feel they're missing anything - what you've never had you cannot miss. What you've had, lost and coped with you've learned not to miss. No one buys into this pedantry but academics with too much time on their hands.
EDIT: I apologize for "proselytizing" and "trashing" that view. My sister is an ASL teacher and she's made the same points you have to me, so I'm aware of the debate, and so have strong views on the matter. I have heard and considered everything you've said beforehand. I believe this sentiment comes from empathy and affirmation of deaf people as taught by those who are close with that community. Yet, I also believe this view is nonsense that someone outside that context can clearly see.
