My problem with NPR is that is the spirit of remaining unbiased, they allow both sides of the political spectrum to say their piece with little to no push back. Whichever side spews the best lines of BS wins regardless of the actual facts on the ground.
This is...kind of an insane take on what NPR does and does not cover?
First, the insinuation that they make an effort to remain unbiased is kinda wild. As an NPR listener and donator, that isn't at all the impression I get. They seem to overwhelmingly cater their coverage and their slant towards people a lot like me. That's why I listen and why I pay and what paying customers actually expect (whether they are consciously aware of how they are supporting and consuming their own preferred bias in media is maybe 50/50 but whatever).
Can’t speak for all of NPR but what I listen to regularly pushes back on claims from both sides. My local affiliate had an especially critical interview with the state governor and the interviewer and governor agreed that they should do these hour long interviews more often.
NPR has been pushing back harder, and will label untruths as "lies" where earlier (circa 2015/16) it was very reluctant to do so. Many news organisations in the US tried very hard through the 2016 campaign cycle to normalise what was a very-far-from-normal. I've recently been going through some Brookings Institution podcasts from ~2012--2016, and the degree to which the hard-right shift was normalised at the time is telling.
NPR in particular avoided the word "lie" as late as 2017, see:
At some point, you the audience member has to be able to whittle down two sides of an argument and determine who "wins", rather than having some broadcaster decide for you.
