A New York Times article highlights the case of Karen Coveler who, after giving birth to a deaf child, found out a simple test could have told her there was a high risk of it happening:

...Dr. Ostrer said that almost no one offered [the deafness test], including the genetic counselors he supervises, because of opposition from advocates for the deaf who argued that deafness was not a disease.

'If people ask us, 'What about that deaf test I heard about?' we will tell them about it,'' Dr. Ostrer said, 'But we aren't more proactive about it because of the sensitivities of the deaf community.''"

Question: if a treatment that allowed deaf people to hear was invented, how many would refuse it on the grounds that deafness is not a disease?

This is political correctness run amock.
