Sadly scotcel, I feel the polarisation which we now have in politics has left us with a situation where truth has become a casualty. I can't speak about the broadcasting organisation you speak of, I've only watched the odd programme here and there.
But the rise in politically driven media has all but crushed genuine debate in my opinion. Especially in America. Those stations, right and left, are perfectly aware of the preferences of their audience. They control the narrative to suit.
I get the impression you like to read, as I do, about politics . Ezra Klein's book titled Why We're Polarized, is the best I've read in a long time. Well worth a look.
