If you are talking about anything caused by our genes someday we could all be just a few approved clones of what the people in power think is "best". Over-correction of natural variation can be dangerous for a species' survival. At least this author thinks so: http://www.amazon.com/Children-Of-Prometheus-Accelerating-Ev...
Are all neurological disorders like cancer? How do you apply this to autistics? Is our perspective on the world and our specific neurology a feared disease, should it be? DS people ask very similar questions.
Autism is labeled as a "neurological disorder", do you like to apply these opinions to autistic people who want to keep their selves that have thus far developed? You "cure autism" and you remove all of the interactions that person's brain had with the world around them and the perspectives their neurology causes [?].
Ask this about autism and see what kind of "caregivers" are out there. Or, if you as a parent could not get services for your DS or autistic child, would you get a lighter sentence for the all-too-common DS and autistic murders out there? [The press treats caregiver originated murders gingerly too.] Autistic rights groups follow these developments painstakingly, often in dread of what the wider public incorrectly assumes from these very basic studies.[I hate science sensationalism with a passion.]
