Inflicting deafness is absolute, unmitigated cruelty. The so called "deaf culture" is a sick cult-like group with extremist memes that glorify a defect.
Deafness isn't a feature, it's a bug. It's a crippling disability, and destroys any chance at normal social interactions from birth, requiring significant extra effort by every individual in the deaf person's life to accommodate. It easily leads to depression, antisocial behavior, and other psychological issues.
Worst of all, it restricts the person from experiencing all of the music, conversation, nature and warning alerts and laughter and the vast beautiful landscape of sound there is to experience in the world.
Don't enable monsters by trying to be accepting of differences. It's not cosmetic or trivial or cultural, hearing is a fundamental feature of the human experience.
That would open a whole can of worms. What if some society says black skin is a disability so black people shouldn't be allowed to reproduce?
I'm going to put it another way. Does this really pass your own personal sanity check? That parents should be allowed to:
- Amputate their children's limbs (Various developmental defects
- Remove their children's eyes (Blindness)
- Perforate their children's eardrums (Deafness)
- Remove their tongue / vocal chords (Mutes)
- Paralyze their kids (Various forms of musculoskeletal issues)
- Inflict brain damage on their kids (various forms of intellectual disabilities)
I left it out intentionally as while I personally think it's in the same category, it's unfortunately sufficiently normalized as to pass without question.
Here, I'd probably have that be legal. Not because I approve of it, but because the alternative, regulating who gets to reproduce, is worse.
As for the existing cases of child abuse, we've already got things for that. We have anti-child abuse laws and their like. They're not perfect, but they denote a line of behavior beyond which is not tolerated.
It worked like that a few hundred thousand years ago and we seem to have mostly collectively decided as a species that this was not the way to go
