Some time ago, a chap named Mark Fiore created this cartoon parodying the teabaggers:
Well, Bill O'Reilly took the time to attack him on his TV show. Soon after, he started receiving death threats. And on a related note, Charles Johnson, the blogger behind Little Green Footballs, also received threats after his announced break with the right, and has moved into a gated community for his own safety.
Thanks to Blaque for both stories.
