What the other people said, but what made me say that was how SO many parents talk constantly about how their child "keeps up with their hearing peers", can go to pizza parties with hearing kids with no problem, has "full access" to the hearing world, etc. etc. etc. They are completely dismissing sign language and deaf peers as an option in addition to using CS and interaction with hearing peers. They have obviously come to use CS as the MAIN form of communication and a way to fit into the hearing world more, NOT just a tool for teaching literacy. They want their deaf child to be as much like a hearing child as possible.
In other words, instead of using CS as another learning tool, they are using it to try to shove their square shaped child into a round shaped hole, rather than accepting that square shaped hole is just as viable for their child as a round one. That is what is being demonized about CS, and rightly so. Parents should never cut their deaf children off from the option of sign language and deaf
peers, and no matter what they choose to use to help their children access the
world that should always be one of the options. Always.
