Wikipedia: Darwinism is a term for the underlying theory in those ideas of Charles Darwin concerning evolution and natural selection. Discussions of Darwinism usually focus on evolution by natural selection, but sometimes Darwinism is taken to mean evolution more broadly, or other ideas not directly associated with the work of Darwin.

Its use as a code wode by Creationists is limited pretty much to the US.

The ideas of natural selection and "survival of the fittest" were originated by Darwin. Even misapplications of these ideas are therefore Darwinian in some sense.

Even misapplications of these ideas are therefore Darwinian in some sense.

Are misapplications of Christianity Christian in some sense?

"survival of the fittest" was a Darwin quote?

Can you prove that? I thought it was another guy named Herman or Herbert.

"The ideas of natural selection and "survival of the fittest" were originated by Darwin."

Natural selection is Darwin's, but survival of the fittest belongs to Herbert Spencer. It isn't used by biologists, and hasn't been for a long time, because the phrase is too imprecise.
