What are you talking about? This graffiti was put up by Jews.
Being a pro-Palestinian Israeli does NOT make them Jews!! There are MANY Israeli hating Arab Israelis who remained when the UN created Israel in 1948 because thery considered it their family home. They may be Israeli citizens, but they are certainly NOT Jews. That's like saying that Obama is an American. He just lives here, but he's an America hating Kenyan!!
