It's exactly what you think it is. Just because the man keeps trying to say he's liberal, doesn't mean he actually is. He keeps throwing out old and tired and debunked maga talking points such as the 'covid's a bioweapon' lie, or the Hunter Biden laptop lie, and then attacks DEI as some boogie man without actually showing any real harm being done by the initiative except to act like older white men's views (read: his views) aren't getting more respect. He also makes the same old tired accusation that NPR and of course "liberal media" is hiding information when in reality, it's only reporting information that it can confirm as factual. It isn't "Steve Inskeep said that covid isn't a bioweapon" it's "XYZ Scientists say covid is not a bioweapon".

In other words, he wants NPR to report on MAGA conspiracy theories like conservative media does. His complaints boil down to claiming that NPR's integrity in journalism isn't fair to conservatives who want to hear unsubstantiated claims that make them feel good, and that's why they lost conservative listeners. He keeps referring to 'viewpoint diversity' as a coded phrase to really mean conservative viewpoints. He keeps trying to act like diversity means having to let nazi's take over the conversation, and to not let them do so makes the organization a hypocrite. Again, that's a tired and old conservative talking point. And of course like every white guy surrounded by diversity initiatives, he thinks he's the only rational person in the room and must call out the insanity of diversity initiatives as some secret evil that only his eyes can see.

Dude should go work at Fox. He'd do great there.
