I watch his show every week, and though I don't always agree with him, I do appreciate some media trying to have honest and open conversations about things, versus just each side yelling at each other side type of conversations.
Having said that, he seems pretty myopic about the whole Israeli-Palestinian-Hamas thing going on right now. (But then again, there seems to be a concerted effort being pushed on multiple media outlets like CNN as well right now.)
Also sometimes he gets a little bit into a 'yelling at the clouds to get off his lawn' mode.
But overall, he really tries to get honest conversation going between parties on all sides. I enjoy watching the show every week, including the extra part that is on YouTube afterwards.
