I simply meant that sterilizing those with Down Syndrome would do nothing to "improve the race" or lessen the incidence of the condition. I'm unsure of the eugenicists' actual position on the syndrome, but considering some of the minor conditions they used to classify people as "unfit" (some well within the "normal" variance of human genetics), it seemed likely that they would have considered Down sufferers as unfit, and therefore candidates for segregation or sterilization. It would have been unjustified and fruitless, that's my point.
