That's the thing about propaganda and cultural hegemony (well, one of the things anyway) - the author doesn't necessarily have to have a conscious agenda in order to reaffirm and reproduce the dominant narrative which is based on the agenda of the ruling class. They propagate the agenda just by being steeped in the cultural narrative and taking it as "common sense" without even thinking to analyze it with anything near the kind of scrutiny they apply to other historic cultures. They probably think they're being strictly objective even as they push a very real but unrecognized liberal agenda.
