There is a time to try to calmly reason with offensive wingnuts, who are trying to corrupt people's minds and gain political opportunity by dishonest means. And there is a time to just call them what they are, a bunch of a******s. P&T is like Buzz Aldrin punching Sibrel in the face.
Their show on Global Warming was the only one I questioned. Not because I believe one way or another, but because it still seems undecided. I do agree that conspiracy theory wingnuts have gravitated to the Global-Warming issue. They might be right or wrong, but their reasoning and scientific knowledge is still defective.
In general, I believe most rational intelligent people tend to believe true things. Everyone has a few passionate beliefs that are incorrect, of course. But I'd say about 25 percent of people are able to change their minds if they are shown hard evidence. It's not easy, I really do thing most human beings tend to think in terms of magical associations, not scientifically or logically.
Penn is such a rational person. He's a social liberal, an atheist, knows a lot of science and scientists, and is economically conservative. I think 90 percent of his opinions are correct -- because they are the same as my own.
