The "Gay Gene" and tolerance

Albert Mohler has an interesting article (Is Your Baby Gay? What If You Could Know? What If You Could Do Something About It?) about the implications of finding a biological basis for homosexual attraction: if this trait is proven to be a genetic orientation and is found to be correctable, how will it affect social perceptions about "homosexuals"? It's an interesting question of the tension between tolerance and approbation, and the fact that tolerance is rarely sufficient for the multiculturalist or moral relativist.

This reminded me of a similar discussion with a friend today in relation to people in the deaf community who refuse to provide their deaf children the benefits (in my estimation) of things like cochlear implants. I can only conclude that this attitude of deaf adults is related to concerns about the possible diminution of deaf persons. Can we not all agree that a deaf person--even though handicapped or physically deficient (in regard to the five senses), is worthy of respect and can have dignity?
