In school in Gaza, I learned hate, vengeance and retaliation. Peace was never an option, as it was considered a sign of defeat and weakness. At school we sang songs with verses calling Jews "dogs" (in Arab culture, dogs are considered unclean).
Criticism and questioning were forbidden. When I did either of these, I was told: "Muslims cannot love the enemies of God, and those who do will get no mercy in hell." As a young woman, I visited a Christian friend in Cairo during Friday prayers, and we both heard the verbal attacks on Christians and Jews from the loudspeakers outside the mosque. They said: "May God destroy the infidels and the Jews, the enemies of God. We are not to befriend them or make treaties with them." We heard worshippers respond "Amen".
