Are you suggesting that by aborting a fetus with Down Syndrome, the fetus is then cured of Down Syndrome? You’re not really correcting the developmental defect insomuch as eliminating the fetus that had the defect.

The context here is that there's evidence crispr CAS-9 can be used to repair damage to the genome by specifically targeting and deleting the extra third chromosome inside a living cell. I don't know why you'd assume I'm talking about abortion.
