A controversial ad was posted in four Metro stations under court order Monday, but within hours one had already been covered with yellow Post-it notes giving an alternative message to the ad, which equated Muslims with savages.

Debbie Polhemus, of D.C., covered up the letters of the ad, which read “In Any War Between the Civilized Man and the Savage, Support the Civilized Man. Support Israel. Defeat Jihad.”
