There are three basic ways to talk to complete idiots.
The first is to assail them with facts, truths, scientific data, the commonsensical obviousness of it all. You do this in the very reasonable expectation that it will nudge them away from the ledge of their more ridiculous and paranoid misconceptions because, well, they’re facts, after all, and who can dispute those?
Faced with this mountain of factual obviousness, the bewildered fundamentalist will merely leap back as if you just jabbed him with a flaming homosexual cattle prod, and then fall into a swoon about how neat it is that angels can fly.
