According to the ENCYCLOPEDIA OF WARS by Charles Phillips and Alan Axelrod, religious wars account for only 7%, or 123 of the 1,763 wars in recorded human history.
It is important to note that 66 of those religious wars, more than 50%, involved Islam, the so-called “religion of peace.” Yet, Islam did not even exist as a religion for 3,000 years of recorded human warfare! In that light, please note that the Christian Crusades, especially the first one, were actually a defensive action against the barbarity, violence and warmongering of Islam.
Furthermore, only one of the U.S.A.’s 17 wars, the current “War on Terror,” has involved any religious entanglement (once again against violent, sexist Muslim tyrants), despite the fact that the United States has been one of the most religious nations in the past 221 years of its existence.
Thus, when liberal atheists like Sam Harris (on page 12 of his book THE END OF FAITH) say that humanity’s tendency to slaughter one another “generally have their roots in religion,” he is not telling the truth.
Remember these facts next time you run up against an irrational atheist or loony secular progressive ranting or frothing at the mouth against religion, Christianity, God, the Bible, or “the religious right.”
