Chris Hayes has a great piece on the bizarre world of right-wing chain emails, in which all manner of vicious slurs and lies circulate for months or even years without anyone in the MSM noticing. Sometimes they pop up on a sufficiently mainstream place — Fox News, Rush — for someone in the real press to bother running an item pointing out that the story in question is false, but then the meme just dives back underground again where it lives on.

From time to time, I’ve received these bizarre emails, and every single one of them — I’ve checked them out — is demonstrably false.
