Two words, Steve: Social Darwinism.
The idea was inspired by the theory of evolution, as you well know. As were a whole host of other eugenic (and economic) theories.
I suppose you can ignore the fact that ideas -- even the theory of evolution -- have moral consequences. But of course, anything that has a practical application carries with it a set of moral implications. I rather doubt that you'd claim that evolutionary theory has no practical applications, which leaves you with the problem of dealing with its moral implications.
I'd wager that you are not in favor of Social Darwinism. But in order to be against it (or for it, for that matter), you must make the argument why evolutionary theory cannot (or can) be applied to humankind. The moral implications just sit there, unable to be ignored.
Ah. I see that you're one of those folks who assumes that labels always mean what the common meanings of the words imply.
I assume that only pressing business has kept you from moving to the perfect nation, the Republic that is run for the benefit of the People. When you're able to go, give my regards to Pyongyang.
