At this point I view eugenics as nearly always bad. With most "improvement" we'll most likely reduce our diversity, and that's pretty bad.
I'm inclined to ask why that's bad. Sounds like it would solve race hate problems.
Anyway, I think the problem is likely to be the opposite. More likely that whacky people - the sort that currently name their children things like "Pilot Inspektor" and "Crime Fighter", are also the sort of people who would think it fun to opt for a green baby, one who will grow to 8 ft high, or one with four arms.
