 You probably missed it, but if you were paying close attention to the most recent episode of Homeland, you may have caught a subversive protest written on a wall. In a scene where Carrie Mathison, played by Claire Danes, walks through a refugee camp in Lebanon, the words, "'Homeland is racist' can be seen written in graffiti on a wall. There were other messages, too. There is no Homeland, and Homeland is not a show." The graffiti was planted by a group of three artists who were hired over the summer to design sets for the popular Showtime series. Showtime was looking for artists to tag the sets in Arabic script in order to lend a sense of authenticity. They suggested some generic examples and urged the artists to keep it apolitical, but they apparently didn't follow up. The artists, Heba Amin, Karim Kap, and Stone, seized the opportunity to protest against Homeland, which they say perpetuates misleading stereotypes about the Arab world. Over the course of its run, the show has come under criticism from many who say it presents an inaccurate and biased view of the cultures and places it addresses. Even some governments like Lebanon and Pakistan have publicly taken issue with it. The artists went public with their stunt on Wednesday, a few days after the episode aired in the U.S. In a statement, they called Homeland, "...the most bigoted show on television." It's not yet clear whether Showtime will try to digitally erase the graffiti for future rebroadcasts. In a statement issued this week, showrunner Alex Gunza expressed regret for not catching the stunt before it went to air, though he also complimented the artists for their ingenuity. Because Homeland always strives to be subversive in its own right and a stimulus for conversation, he said, "...we can't help but admire this act of artistic sabotage."
