I guess you could say taking any position to an extreme is bad. However each of these diseases opens paths to future cures. It helps us understand human body better. And those cures will open ways to more ideas, etc. Without diseases we'll never have a chance to explore. I'm not negating those defects don't leave their parents in despair, but I speak from a position of a similar though magnitudes way milder defect (hip displacement). Eugenics taken to extreme would have discarded me. Eugenics on small scales does have some advantages, though I fear it would bring advantages in a way that will only widen inequalities i.e. only people with money would have enough money for it. Rich people wouldn't just have money, but also best looks and best health. Eugenics on large scales is on the other hand simply disastrous as it leaves monoculture and erradication of anything perceived as abnormal.
