Silly objection. There is a dominant Narrative shared by the professoriate, the clerical/adminstirative class in all ranks of the education system, the elite media, most big corportations, the permanent bureaucray in DC and the state capitols, nearly all foundations, all pop culture, and all intellectual organizations that are not explicitly conservative. And even in the last case, the "conservatives" are in on at least some aspects of The Narrative (e.g., open borders).
Which is to say, the commanding heights of intellectual and cultural life in the West are totally dominated by The Narrative. There may be "other narratives" but they have no power in today's America. Thought has been consistently moving in a more and more monothetical direction in my lifefime. And the differences between the left and the so-called right continue to shrink.
