I generally live by the rule that you should not talk about a topic unless you actually know something about it. That can very easily be extended to include representing or endorsing a product/concept/argument as well. Ben Stein … well, it has often been pointed out through various means that he is woefully ignorant of the Theory of Evolution. He simply does not have a clue. Someone has made a rather nice Youtube video which more of less goes through Stein’s silly statements one by one and shows them to be full of the old proverbial. Well worth a watch.
