I will plead that I am using normal in the normative (and thus subjective) fashion but even in a positive fashion you still have to pick the values you choose to measure. You can't simply reduce a phenotype to a single dimension of good/bad and try to push it back to the middle. See for example the giant literature reflecting the many gains of function that accompany learning disabilities. If I take my meds to fix only the 'bad' parts aren't I somehow gaining a leg up because I have an advantage along another dimension? Probably an even better example is bipolar disorder where the current 'fix' makes the person catatonic, a clear loss since they are often highly productive during mania. The reason I bring these up is because they are better edge cases than something like cystic fibrosis (which is a better fit for your argument) where there isn't really much debate (and doesn't fit with the article). Other single gene causes of mental disability might also be a better fit for the 'pure normal' but what happens when we discover a 2 gene source of mental disability? How about 10? How about 100? Where do you draw the line between mental disability and just being stupid? If I feel sorry for zygotes that will grow up to have average IQ because many of the most beautiful things in the universe are beyond their grasp. Does the fact that they will be 'average' mean their parents should be denied the ability to give them the gift of one day having deep insight into the beauties of the universe? This is a longwinded way of saying that I think part of this issues is because many people in our society conflate 'normal' with 'best,' the result is that they argue that it is ok bring someone back to the average but that somehow anything beyond that is immoral. What kind of sick society doesn't want every member to lead the most fulfilling, contributing, and meaningful life possible? Sure there are plenty of arguments about certain treatments being out of reach of the poor, but to bring things back to the original article: have you seen the prices of private schools lately?
