A political action committee set up by the creators of the humorously cynical party game Cards Against Humanity erected a billboard in Dearborn, Michigan this past weekend consisting of an Arabic slogan implying that GOP presidential candidate Donald Trump is afraid of Muslims.

“Donald Trump, he can’t read this, but he is afraid of it,” a translation of the sign reads. Underneath the Arabic message is the web address trumpisscared.org, which consists of a page summarizing what it calls Trump’s inflammatory and inconsistent rhetoric decrying Muslim immigrants. Melissa Harris, a spokesperson for the The Nuisance Committee (the super PAC responsible for the billboard) explained to the Detroit Free Press that its aim is to expose the fear underlying Trump’s stance on immigration: 

“We came up with it because we believe that Donald Trump’s hateful rhetoric is not based on reality. It’s based in fear,” Nuisance Committee spokeswoman Melissa Harris said of the Republican presidential nominee. “And we think that irrational fear is what’s driving his anti-immigrant message.”

She said Dearborn was selected because of its high population of Arab Americans in a swing state. They’re hoping the message spurs conversation, with people reaching out to Arabic speakers to ask what it means, Harris said.

The group is funding its political efforts via America Votes with Cards Against Humanity, a web site hawking Donald Trump and Hillary Clinton expansion packs for the game. A statement on the web site reads:

At the end of this promotion, Cards Against Humanity will tally up the sales of both packs, and depending on which pack gets more support, we will donate all the money in support of Hillary Clinton’s campaign.
