I mean the basics of natural selection, and why it's important not to mix them up with degenerated popular culture derivatives, and why applying the latter is pseudoscientific, are basically scepticism 101.
It's a mistake that the best of make for sure, but we have to expect that we be called on it, and admit to having made a mistake, if we do happen to make one. ESPECIALLY someone like Randi (or, for example, Penn) who is perceived as an... authority of scepticism in many eyes is the committer of said mistake.
