Hrmm, every episode I've seen of O'Reilly, Beck, and Hannity makes me shake my head. I have quite a few friends who are right and love their shows, a few even think their shows are real news and not opinions, so I end up watching more of their stuff than I care to admit. Not everything they say is drivel, but too much makes me end up breaking out my internet phone as they talk and back checking their facts as I can.
My problem is that shows lately are way to opinionated period. When I watch news I like it Dragnet style, "Just the facts mam." But just the facts don't get ratings. So what we end up getting is the crap that is on TV. This is one of the reasons I don't bother watching TV at all. Rather read the news so I can filter through factual information easier. It's way to easy to be caught up in the "intensity" of the person preaching to you and end up believing what they say.
Oh for a side note, it took me a bit to convince one of my Right wing friends that loves Beck, who typically spouts that America was founded by Christians, that the majority of the founding fathers were Deists and not Christians.
