I guess the question for me is, if they have a hearing child, what's stopping that child from being a part of their parents' culture?

If a Deaf couple had two children, one with hearing and one without, would the hearing child be excluded from the community and only the non-hearing child welcomed?

Or is the worry that the hearing child will leave the Deaf community and move on to greener pastures once they grow up, while the non-hearing child will have no choice but to stay?

Either way, it paints a pretty grim picture.
