I've heard of this before--deaf people have a "culture" that is unique, one they want protected. Some will protect it to the degree that they won't allow their children to have cochlear implants so the children can hear.
What constitutes a "culture"?
I recommend this very short article from the Independent Gay Forum. The article works from the supposition that if it's ok for deaf people to have their culture, would it be ok for parents to somehow, through the miracles of modern technology, "de-gay" their children in the womb so as to perpetuate heterosexual "culture"? "Designer babies" have already been addressed on the covers of leading news magazines; would it be acceptable to have "heterosexual" as one of the attributes? Would it be acceptable to have "deaf" as one of the attributes?
The comments (16 as of when I type this) display some very astute observations and raise some very interesting questions. Hey conservatives! Get past the name of the web site and go expand your horizons.
