What are those statements that "might be true"? It's hard to come up with better candidates than Cofnas' theories.
(As an aside, Graham likes to talk a lot about Galileo (in this essay and many others); he makes him a hero of truth. But Galileo didn't get into trouble because of his theories! But because of his attitude. He would ridicule the papacy, in writing, repeatedly. What you couldn't say wasn't that the earth moved, but that the Pope was a clown.)
