Website I'd Like To Correct

From Power Line:

I don't think there is any precedent in our history for the shameful manner in which the Left has treated Sarah Palin. Left-winger Andrew Sullivan gleefully posted a particularly disgusting example of the phenomenon today; it's a YouTube video titled "Red, White and MILF." Watch it only if you have a strong stomach. If you don't know what "MILF" means--I'm sure most of our readers don't--Google it.

This is shocking. A writer at a high traffic spot on the internet doesn't believe his readers know what MILF means? Everyone knows what a MILF is.
