COVID: Two False Narratives

It’s not farfetched, if you stop to consider it. CNN’s viewers expect them to… how to put this diplomatically?… to err on the side of safety (and if at all possible, the Democratic Party). And Fox’s audience is used to them opposing CNN as much as is possible. So it’s not at all unreasonable to expect that both narratives are, as AOC famously put it, factually incorrect but morally right.

In this particular example, the narratives are driven by different ways to measure the danger of COVID.
