I'm thinking that it was likely local programming, and KPCC has call-in shows (Talk of the City - local, Talk of the Nation - which is NPR, Air Talk - local) while KCRW has "editorial" shows (Which Way LA - local, To the Point - national version of the same show)...

I'm not excusing the local programming, but KPFK has the same thing. Only they tend to bash people who don't agree with them. I have heard it. They also come across as extremely intolerant.

But that's in my experience only. Your mileage may vary.
