That's what the Pew Research folks say.
And you know what?
That's about the same percentage polled who think Elvis is alive, or that astrology has scientific merit.
Or that Bigfoot is real or that George W. Bush had advance knowledge that the World Trade Center was going to be hit.
Wacky people walk among us, and their showing in polls has been noticed here.
(And no, this is not a criticism of Eugene Kane, who writes about this topic today also. He's right. It's ridiculous that we are having this discussion, but that's because there is a percentage of the population that you can't reason with.)
