Earlier quoted context omitted.
Of course. All anthropological work about contemporary society seeks to inform public opinion which dictates policy.
They're not prescribing any policy in the paper. But you seem to be saying it's impossible to write about your observations of humans without having some ulterior political motive. This seems pretty tenuous, can you back it up? What policy do you think the authors are trying to secretly advocate for?
My point is that studies seek to inform on their areas of focus. Particle physics spending policy does not affect social issues. Anthropology of contemporary society does.
