Not a historian, but I think the whole issue is very complicated. Eugenics was, at the time, mainstream and fairly widely accepted as a great idea. I'm sure well meaning people right now (myself included) are promoting ideas that will seem off-putting in the future. No need to honor these men, of course, but I think it is important to take the historical context into account when personally judging. There but for the grace of god go I, kind of thing.
