I feel like, rather than sitting around complain about how much "hearing parents don't understand", the Deaf community needs to build bridges. Parents give their children CI's because they work! They see dozens of other deaf kids with them, at school, in playgroups, etc, and they see that they work, and they want the same benefit for their child. Most parents also read research and talk to professionals, and come to the conclusion that a CI is right for their family. There is nothing you can do about that, it's going to continue.
The change can happen in the next step. We need to show parent how ASL can benefit an implanted child. Don't tell them that all deaf children will fail without ASL, they know that isn't true. Don't say that CI's are fake and don't work, they see that they DO, with their own child. Parents need to be welcomed and to see that the Deaf community, and by extention, Deaf schools, are diverse and include people like their child.
Call them lazy, ignorant, unaccepting, "genocidal", or commiters of "hate crimes" and you are only hurting the deaf. You are ensuring that another deaf child goes without ASL and the Deaf community, and creating another mom like "cochlear implant online"
] Of course, like every other parent with a child who's gotten a CI or is considering it, I've got stacks and stacks of medical stats and studies and journals and data -- of the scores of parents of deaf kids I've encountered who have considered a CI, I've never meet a single person who has gone into it without doing extraordinary amounts of research. Today, I think parents have great access to research and data no matter what the issue is, from buying the right bicycle for a child to looking into just what that particular cold medicine does to a wee one -- so for surgery, I can't imagine anyone not investigating thoroughly and using their good judgment to winnow out the nonsense. But I also think you can't really get the full sense of what kids are doing and how they are interacting with the world by looking at device lifespans, audiology scores, vocabulary levels, or even points on a "rank your satisfaction with life in general" scale. I needed to read her own words or look a kid in the face and watch or listen to the way he expresses himself to get some degree of insight into whether or not she or he is happy and thriving or feels hurt, limited or shackled by educational and language choices or the technology available or not available to him. Videos and blogs and facebook aren't perfect for this, but you can really get a lot out of these sources, actually probably more than you might get in person with some teenagers
