It’s not as stupid. The article they are talking about pertains to how the dominant viewpoint for understanding reality and the things that happen in it is narrative-based. It tries to explain its flaws and suggests alternatives. It doesn’t really ask you to “reject narratives” altogether as much as to have more than one tool in your arsenal to model reality.

As for his point about modernity rejecting stories, I am not sure about that. I think he is half right that liberalism promotes decontextualising world history. But I think that linear narrative based way of understanding is very common when talking about events that happen over shorter time frames.
