The only use that Progressives make of Darwin is as a weapon and a bulwark against God and the Christian religion. His theory destroys the Bible and frees them from any need to wonder about their destiny beyond this world. That is their only interest in him.
Because after that, Progressives immediately turn to acting as if the species homo sapiens is entirely exempt from everything we know about the rough, violent and unforgiving process of Darwinian evolution. They demand that we live like angels.
All people are equal, and there is no danger whatever in filling your territory with masses of competitors, and both race and gender are merely societal fictions, and warfare is not natural, etc.
The Six Day creation in a concrete reading of Genesis makes more sense.
