I don't think that's fair. The first article explains the WHO position, it does not endorse it.
In the context of left-wing political activity, just:
> In the midst of the coronavirus pandemic
In the context of right-wing political activity, a far more frightening description:
> despite the deadly coronavirus pandemic, which continues to wreak havoc on the lives and livelihoods of households across the country.
If NPR didn't lean left, the second article could have started with a tone similar to the first: in the midst of the coronavirus pandemic, the Trump campaign will address another pressing issue, restarting the American economy. The rally has prompted fears that the close contact of thousands of attendees could lead to a spike in case counts.
What is the political orientation of a "mass gathering" (rally/protest/etc) if not its purpose? Seriously.
> It's not the political orientation of the mass gathering - it's the purpose. One is the President organising a gathering in an attempt to boost his election campaign - the other is some random people who came together to protest a specific thing.
How does the purpose of a public gathering alter a virus? Does it have political awareness and dynamically modify its transmissibility according to the righteousness of the cause?
Or perhaps the purpose of a public gathering justifies journalistic framing (altering the description of the severity of the virus, which in turn alters readers mental model of reality). If it's this, what is the logic behind the justification?
(Plus, Trump's rally was indoors; protests are outdoors. We've got quite a bit of data now indicating outdoor transmission is less likely.)
