According to one Deaf person in a deaf forum he felt that deaf babies and toddlers ought to be cured for their hearing loss if stem cell proved successful and see that a law making it mandatory for them to be treated.

stem cell consistently proves to be 100% successful, I will have unwavering support for it and will want to see a law making it mandatory for toddlers, not adults.

Agree or disagree? That day may actually come, and it'd simply be a matter of time. And this is a contention that worries many people.
