I can only speak for myself ~ my anger comes from being able to communicate with Deaf people (and deaf people) better than their parents & I don't have Deafness in my family. It is frustrating when it is LAZINESS (what else do you call living in a home with someone their whole life without learning their language???) of the parents and families involved.
Braille is ENGLISH, blind people speak ENGLISH, they socialize with others blind or not, they belong to the culture of their LANGUAGE/society.
ASL is a LANGUAGE in it's own right, Deaf people have fought for years to have this recognized and it has been documented as the NATIVE LANGUAGE of all deaf/Deaf people~period. With the language comes a culture of its own.
All I ask of these parents and those who know *nothing* about this, LEARN!!! Do your homework, find out what is available before FIXING what the child may not consider broken. Find anyway possible to communicate with your child, in the way most accomodating to the CHILD not to the Hearing members of the family.
I, for one, would not freak if I had a deaf child ~s/he would grow and thrive as a Deaf person, linguistically and culturally. Yeah, this means they would have a life different and sometimes separate from mine. My experience has shown that this is NO BIG DEAL with parents who can communicate with their child in their rightful native language.
I would never deny parents the option of fixing something like blindness, clubfoot or cleft palate as you asked. NEVER! Again, I will state, these procedures have long term studies done about them, they do not involve placing electronic devices inside someones BRAIN without their consent/understanding. Deaf Culture is something near and dear to my heart, I would hate to see *lazy* Hearing people wipe out yet another culture they don't/won't understand! Please, go out and meet some Deaf people yourself, ask them, most will be happy to discuss this hotly debated topic with you. Get your info from the Source yourself, I did.
