You should examine my FR page and pay careful attention to how many "insane" and "crazy" eugenists were darwin medalists, prominent darwinians, and members of darwin's family.
I asked Wikipedia about “darwinians” or “darwinists” and as result I get “Darwinism”. Darwinism is not the same thing as the “theory of evolution” or short “evolution” if the context is clear.
Also you can't disprove a theory because some idiots build a bomb - Alfred Nobel, chemistry - or bigger bomb - Einstein, Hahn, Szilard, Oppenheimer..., atom theory - or a rocket to deliver a bomb - Wernher von Braun.
As I read it “Darwinism” is about the social impact of the “theory of evolution”.
All you got within science are theories. Nothing is proven within science. You can only disprove something.
