Don't tell me again about the moral imperative to denounce Nazis if you're going to let this slide.
As Rob mentioned to me when we were discussing who would write this up, the essence of Hitler's eugenics program was to filter out children who didn't have the traits deemed optimal for the Aryan race. Horrifying? Obviously. You'd have a fit if they started aborting babies for having brown skin, or - if there was some way you could tell - for being gay.
