I agree with you that most of these religious leaders are buffoons. They feel compelled to speak out on every political issue and end up spewing platitudes that amount to, “The US is arrogant...rich people are bad...peace is good.” Notice how all the lefties love the United Nations...until they really want something to get done, and then they start whining for the U.S. to get involved? All of them can go scratch.
C.S. Lewis said it best (I don't have the quote at hand but it's pretty close) -- "The only thing a political sermon tells you is which newspapers are taken at the rectory."
