People always want simple ideas and black/white thinking because the human brain is not evolved to cope with complexity. Not surprisingly, therefore, a complex idea like evolution is constantly dumbed down and distorted by those who want to promote not scientific ideas but rather mere self-serving propaganda. Furthermore, people also endlessly conflate arbitrary notions of "morality" with misunderstood snippets of evolutionary theory and invariably end up spouting abject nonsense. It's a real shame, because evolution is (a) an established fact, (b) a beautiful illustration of the laws of thermodynamics, and (c) has great predictive capability for those capable of grasping its essence and applying its rules.
