I find it odd that anyone would relate selective breeding to Hitler, when in fact Germany was the last nation to try such things. Japan, several South American countries, China, India, the U.S.A., Israel, and most of Europe have in the past, or currently are, doing things to facilitate selective breeding.
Even as far back as B.C., the ancient Spartans used to selectively breed for physical strength which made them very powerful. Too bad though they chose physical strength over intelligence: these morons chose ape-like features over cognitive abilities, and then wiped out Athens, a truly intellectual society. Oh well.
