So, let me get this straight: My fiancee, who was hearing until age 12, has more authority to speak about deaf babies (from what you've told me), despite this quote? And I, a hearing person, have the right to speak out about deaf babies too? This doesn't make sense. Not to be rude or anything, but I do suggest thinking carefully before posting so we don't have these ego conflicts and confusing "logic".
True; that point needs to be addressed to implant candidates and parents first. But you're kinda preaching to people who talk about this stuff a lot, so most of us know that.
Huh? 
One fundamental belief I have about this whole thing is that neither the deaf world nor the hearing world is better. They're different, yes, but neither is better.
