Lately I've heard a lot of liberals try to defend David Letterman by saying that his remarks about Governor Palin and her daughter were just a joke and that conservatives should just get over it. To them I have one thing to say...
"A nigger, a wetback, and a fag walk into a bar..."
It's just a joke, right? Sure it's in poor taste and highly offensive to boot but it's still just a joke. But I'll bet you the vast majority of Letterman's supporters would be clamoring for his head, and rightly so, if that was the joke he made instead of calling the Governor and her daughter sluts.
What Letterman said was highly offensive and saying it was just a joke is no defense.
