I've seen four or five replies to this post, and it strikes me that those responding have called it insulting, irrelevant, etc. I too don't see its particular relevance to this list, but I find it interesting that no one bothered to ask if it is true. I have seen similar statistics elsewhere, including the books of Charles Sykes. Someone noted that the post at least let us know what kind of arguments we may face. But may it not also tell us something about the people whom we will have to influence (or bypass)?

The reader is of course, at liberty to believe this happened accidentally, or that the moon is composed of blue, not green cheese as is popularly believed.
