So first of all, I absolutely agree that it's an important concept: to me the idea is one of imitating externally observable behavior, patterns, what-not, without any understanding of what's going on underneath. Unlike what the author says, "cargo cult science" certainly can get some sorts of results; particularly when the desired results are actually things like "grant money".

I'm still processing the information from the blog somewhat; but at the moment, for me, it doesn't come down so much to the idea that these people may be offended, but that it defames them. The story as told in popular culture gives people a skewed idea of what the cultists are like, and reinforces a skewed and arrogant idea about how much better / scientific / whatever the rest of us are. These skewed views hurt both us and the cultists.
It may be, like the "frog slowly boiling" myth, that it's the sort of thing you repeat even knowing that it's not something that actually happens.
Or maybe we need to come up with a different name for it -- although it's not as easy to come up with a picture that's as evocative as the pop culture version of the cargo cult.
