Consider the evils the creationoids -- in their supreme ignorance -- attribute to Darwin's work: communism, racism, eugenics, Hitler, Stalin, etc. You've already pointed out the example of the Spartans and eugenics. We've long been showing that Stalin opposed Darwinian teaching. And I've recently given clear authority (in Mein Kampf itself) that Hitler was a creationist.
As for racism, one must be a genuine moron not to realize that it's as old as humanity. Indeed, if you want to deal in historic sequences as if they were cause and effect, we should consider that Darwin's scientific career was remarkably timed to coincide with the English and American drive to end slavery and ultimately to end the legalized institution of racism. Amazing what scientific enlightenment will do.
And then there's communism. I've previously given examples of pre-Darwinian communism, from the Spartans (what a useful group!) to the Mayflower passengers. Notwithstanding all these clear historical examples, the creationoids will continue to repeat their mantra -- thus demonstrating not only their educational deficiencies, but their intellectual and ethical deficiencies as well.
You point to Stalin as if he was the only Communist that ever lived. Communism did and still promotes materialistic evolution. Stalin's attack on Darwinism was the passing fancy of an insane man who killed not just Darwinians, but religious people. A man who killed not only those of other nationalities, but his own Georgian people. A man who killed not only those opposing Communism, but also his own Communist friends who fought side by side with him in establishing that atheistic doctrine on his nation.
Indeed, the idea of "the children of Ham" was used to justify slavery for centuries before Darwin was born.
