***It doesn't matter that they're a small minority, it matters whether or not they are arguing from the facts using the scientific method. When Richard Feynman was pushing his subatomic theory, he was the only one for a while. It turned out he was right, and the accepted evidence against his position was wrong. Using your line of reasoning, we would deny him the voice (and the consequent Nobel Prize) because he was such a small minority.
True in theory. However, if the facts are imagined to be good, you have to wonder why almost none are convinced given the time ID has been touted and the attention it has created for itself. And, as the lead article of this thread makes marvelously clear, the claims of ID indeed do not stand up to examination.

Feynman was simply the only one out there where he was at the time. He also had a testable theory and was superbly capable of making a case for it. ID has only vague mumbles about somebody having designed something sometime, a smokescreen for witch doctors who don't believe in a nature that can run without the constant intervention of supernatural beings. Witch Doctor science.
