Not interested in challenging deaf people? They ARE deaf people, what do you mean by that?
In my case, my daughter is too young to write and join an online community. I'm hearing, yet part of the deaf community in order to understand and learn whatever I can from those who have trodden the path before and to make it possible for her to be exposed to Deaf culture and those with common experiences as a child. If I were not participating, she would not otherwise have an opportunity to interact with those who are deaf.
I know quite a few older children with CIs who do not participate in online forums such as this because -- frankly -- what is there for teenagers here, whether deaf or hearing? Are there a whole bunch of 14 - 20 YO unaided deaf here speaking for themselves? They are all out there looking for fun and friendship, their friends are on Facebook, the people they know in school, in real life. The experiences being related here are rarely relevant to today's high school age kids who've been wearing CIs since they were 1 or 2: they didn't grow up in the old oral schools described here, they likely didn't have a bi-bi program nearby, they grew up in communities of HA/CI children like themselves or in mainstream environments. The oldest early implantees, the pioneers who got their CIs pre-FDA approval trials, are 21, right? And until recently the Deaf community rejected them and their families outright. So they don't see the Deaf as their own "People." There are not yet 30 - 40 YOs out there who have grown up with CIs from toddler years.
