"Voting is no way to answer technical questions, though it may give pleasure to the voters. This author, a physicist, would hate to see the validity of the theory of relativity put to a vote. If that sounds elitist, it should. It is an unpopular but sound principle that you ought to know something about a subject before you earn the right to express an opinion about it. The schools now teach the opposite—but your view is as “valid” as anyone else’s, no matter how little you know. That not only encourages self-esteem, it rewards sloth."
