What I really didn't understand was the wish to actually have a deaf child. I can understand that if your child was deaf you would love it (him or her) just the same, but to proactively choose to have a child who cannot hear almost seems perverse.

Surely the same thing would be for a couple who say for example, both cannot walk and use wheelchairs, to say they want a baby who also will have to have a wheelchair. It just seems a very alien concept to me, to actually think in that way.
