While I was still participating in the forum for Koala Wallop, which used to host Dresden Codak, there was a prominent and controversial member, John Nyzell, who was a fairly prominent activist in Sweden. He said that he occasionally received death threats from members of the Deaf community due to his public stand against the use of preimplantation genetic diagnosis by deaf parents to select for congenitally deaf children.

For Deaf people, at least (and deaf is not the same thing as Deaf,) it's not that they consider deafness favorable, so much as being able to hear would destroy their culture. They have social norms and values that are dependent on an inability to hear, and they're very defensive of them.
