Thanks, but no thanks.
We already dealt with this issue in the 1940's It only cost us about 400,000 good man and women
We already have social services to deal with "animals" like these. They simply have to do their jobs.
Hitler wasn't sterilizing people for viciously beating their helpless children. He was killing people for being Jewish (and a few other categories he didn't like). Comparing a proposal to sterilize animals like these two child-murderers, to the activities of the Third Reich, is obscene.
