How can Justine Ferrari (Inquirer, 18-19/3) discuss the Crusades without mentioning the massacres of Jews by Christians that occurred? She also ignores the attacks by the Catholic Crusaders on Orthodox Christians that culminated in the sacking of Constantinople in 1204. Pope John Paul II apologised in 2001 for this shameful act.
