Several people have branded my belief that large-scale evolution is a sacred belief a "conspiracy theory." I would like to point out that many of these same people have visited Ray's blog where people are claiming that the educational system is trying to brainwash student into atheism and evolution. How often has this been claimed to be a conspiracy theory? By my count, never. Simply put, it is a conspiracy theory and calling it such is not an argument against it. Saying "that's a conspiracy theory" would probably elicit a response like "that's because there's a conspiracy." Calling something a conspiracy theory when it is one is pointless to an argument. Conspiracies do happen. For example, we wouldn't need laws against corporate espionage unless corporate espionage (a type of conspiracy) occurred. Some go on for years before being exposed. Likely, some are never exposed.
On the other hand, calling something a "conspiracy theory" when it is not may serve as a useful distraction in an argument. It can put the target off his guard and draw out an emotional response. It isn't a logical argument against an opponent's position, or even a pointing out of a fallacy in an opponent's position. It is only a distraction that can prevent clear thinking so that the opponent cannot defend his position.
No, I don't believe that anyone who charges me with "conspiracy theory" is sincere. Simply put, if you really believed that I was engaged in conspiracy theory, you would not say so (at least, not during the course of the argument.) There is nothing that could be accomplished by doing so.
