The author clearly means to mock other people's perception of the natives as "stupid savages", as implied by directly following this statement with "Except, this is a perfect metaphor for most of what is called “science,” done by people with PhDs". It implies that the people that would say that are the ones getting their science PhDs, who are doing the same thing while being full of themselves as superior. You seem to recognize this, by referring to it as being used "tongue in cheek." So, to be clear: You are offended that the author used an offensive phrase in an ironic manner clearly meant to both vindicate the targeted minority and point out the failings of the people that would use that offensive phrase in earnest? In short, you're now upset by the form of the communication, rather than any of its actual content or meaning. Another commenter suggested that you are partaking in some cargo culting of your own. I think they're onto something.
