first of all, The only reason they don't get attack by their own kind because ..... well because they are their own kind.
Second, Some people expect deaf people to accept their view on deafness that is totally unacceptable. Sure there will be deaf who don't bother educating them, but if these hearing want to stereotype deaf people ,because of a few horrible deaf person, without trying to understand where deaf community are coming from, then they are showing racist-type attitude.
BTW, you know very well why some deaf people are against CI. They just don't want people to view that deaf is bad hearing is the only way to survive. Does it mean they have the rights to tell their children horrible things? No. But these deaf do have the rights to express how they feel about CI and what it does to their deaf identity
