"Calling people names is bad, but calling people names based on your own invented calumny is the textbook definition of slander. The First Amendment does not protect you from that, nor should it. Even on an issue of public debate, and even if the victim is a public figure, as Ms. Fluke was here, ‘fair comment’ is not a defense if you made up the central fact, and the central fact is wrong and is damaging and if your intent was to injure. I’m no lawyer, but as I see it: Check, check, check, check."

Gene Weingarten, on why Sandra Fluke should probably sue Rush Limbaugh.
