It took just a few hours for someone to attempt to obscure a controversial anti-Muslim advertisement that went up yesterday in four Metrorail stations. But unlike in New York, where an activist who spray-painted over the same ad was arrested and briefly detained by police, a teacher who covered a display with Post-It Notes at the Takoma Metro station will not face any legal retribution for her protest.

The ads, paid for by a group called the American Freedom Defense Initiative, equates Muslims with “savages” and calls on Metro customers to support Israel and “defeat jihad.” The campaign has also been seen in transit systems in New York and San Francisco, and though Metro dragged its feet for as long as possible before allowing the ads to go on display, a federal judge ruled last week that they constitute protected speech.

The Takoma billboard was plastered in Post-Its by high-school teacher Debbie Polhemus, The Washington Examiner reports. Polhemus’ tactic was meant to be peaceful, though, unlike the spray-painting that got the Egyptian-American writer Mona Eltahawy arrested when she took on the New York version of the ad.

According to the Examiner:

The high school teacher said she wanted to counteract the American Freedom Defense Initiative’s right to free speech with her own right to free speech, all without actually defacing the sign. “This is a public space, and we don’t like hate speech,” she told The Washington Examiner. “And not to do anything would be to allow this speech. … It would be hurtful.”

And Metro spokesman Dan Stessel told DCist in an email that Polhemus’ protest went down without incident, though the Post-Its were quickly removed and she was not arrested or cited for vandalism of Metro property.
