The key to being a religious zealot is to criticize (real or made-up) characteristics of other religions while ignoring the very same characteristics in your own:
The earliest writings that are known to exist about the Prophet Mohammad were recorded 120 years after his death. All of the Islamic writings (the Koran and the Hadith, the biographies, the traditions and histories) are confused, contradictory and inconsistent. Maybe Mohammad never existed. We have no conclusive account about what he said or did. Yet Moslems follow the destructive teachings of Islam without question.
You could say the exact same thing about Jesus of Nazareth and the gospels. Muhammad’s existence is corroborated by contemporary non-Muslim sources and is just as much a historical fact as that of Jesus of Nazareth.
Islamic Law is totalitarian in nature. There is no separation of church and state. It is irrational. It is supposedly immutable and cannot be changed. It must be accepted without criticism.
The separation of church and state is a modern concept that dates back to the late eighteenth century. As for totalitarianism, irrationality and immutability: Have you actually read Exodus and Leviticus?
A Muslim does not have the right to change his religion. Apostasy is punishable by death.
