That's a phrasing-based argument, it disappears if you replace it with "you don't want your kid to be deaf or blind."

I don't think there's anything wrong with having a blind or deaf kid. I take issue with the idea that given the technology we would refuse to fix their disability before they are born.

Try explaining to your son or daughter that they could've been able to see and hear, but you refused to avoid hurting the feelings of existing blind and deaf people...

more like try explaining to your son or daughter that they wouldn't have been born at all

> "Blind or deaf people would probably feel pretty bad hearing 'you don't want a blind or deaf kid'"

I am legally blind. I would not want my children to have any disability whatsoever because it's difficult and miserable.
