I wonder how many of these obviously sane individuals that think it's better to maybe make a genetic issue spread like wildfire, condemning many generations to a range of social and functional disabilities, would be like: you know doc, don't take my tumor out, my body made it so it should never be removed from the equation. It will make me who I am until it kills me in 3 years. I'd personally extend this sort of thing to cancer stuff too, as we can see genetics does play a part. Of course make it purely informational so you KNOW that you'd be having a kid with over 50% risk of autism, or Alzheimer... or schizophrenia.
