It was American physicist Steven Weinberg who said, “Evil people do evil. Good people do good, but for good people to do evil — that takes religion.” Well, Boko Haram, al-Qaida, ISIS and other smaller groups, have vividly proven this point. They really believe they are good people working for a godly cause. Some people say that these groups do not represent Islam. These terrorists may have a different interpretation of Islam, however, their holy book is the Koran, their prophet is Muhammad and this fact makes their religion Islam.
Islam and most religions have no problem condemning whatever does not fit their dogmas. However, they are themselves intolerant of criticism. Some groups will take their intolerance to any length to achieve their religious objectives, including killing and maiming for something as trivial as stupid cartoons, as in the case of Charley Hebdo.
Criticism should be encouraged in a free country. It persuades a society to move forward. It was through criticism that Voltaire stopped the fanatical intolerance of the Catholic Church. He helped enlighten France and other European countries with his criticism of religion. Perhaps, Islam needs its own Voltaire.
