My colleague Rosa Doherty had the unenviable task of covering the annual pro-Palestinian Al Quds rally in London last Friday. When she identified herself, a female marcher greeted her thus, "Eugh, Jew. Blood is on your hands." Feeling scared, Rosa was reassured by a friendly man waving a Hizbollah flag, who said, "Don't worry about her, she's a Christian, they're nuts."
