I find it a real stretch to construe Crockford's use of the word “promiscuous” as a pejorative. Given the context, his usage of the word was apt and descriptive (promiscuous does not necessarily refer to sexuality) without negative connotations; he actually made the opposite case: “that's good because that allows us to get introduced to things”.
