They do talk to conservatives a lot though. Many recent episodes interviewed Trump voters and sent reporters to Republican rallies to hear those "good points" from the source...
Yeah, I didn't say they never cover them. They do it -- to their credit -- and I'd even go so far as to say that they're one of the more balanced programs on public radio.
But they're still far from actually balanced. As a frequent listener, I'd characterize their overall coverage of conservatives as "a bemused, curious foreign tourist".
No, it means "balanced". You shouldn't hide the ugly parts, but you should report on the good arguments of the opposition -- as well as the ugly parts of your own team. Both the left and the right have good arguments and bad arguments, and if you don't believe that, you're misinformed.
Partisans would much rather that they only hear about the ugly parts of the opposition, and never hear about the ugly parts of their own tribe.
