The real problem is more than just burning Koran's or Bibles. The real root cause of the problem is organized religion. An individual or a small group of individuals is given political power over others on account of their being "spiritual leaders". Then we are surprised when those who lead the religion behave like idiots, zealots or megalomaniacs. I am sorry to say that in most churches (or mosques, sinagogues, temples, etc.) that I have seen, people are herded like sheep, all because that sheep instinct allows them to overcome any doubts they might have about their own beliefs. Then most people believe blindly. Most people don't realize that the religion they follow might have been born centuries ago, but its current beliefs might have sprung only in the last 300 years because most current organized religious sects did not exist before the Renaissance and the Enlightenment.

Everyone is trying to impose human limitations on an infinite God, and the belief that a single book can contain EVERYTHING that there is to know about God is the worst limitation of all. Let us describe God in a book written centuries ago, by people who were not even there when the events happened, in a language other than that of the original creator of the religion. Then let's call that book the ultimate truth and base our organized religion (and political power) around that book. My interpretation of that book is the ultimate truth and if you don't believe it you will go to hell, or worse, I will grab a weapon and kill you. I will call my country a "my-religion country" (like contries in the Middle East call themselves Islamic, or the US calls itself a Christian country, or Israel a country for the Jews). Then if I am really stupid I will kill those who don't fit my country's religion, and if I want to claim some higher moral ground I will "tolerate" those of other religions.

And at the root cause of human stupidity sits organized religion and the sheep that follow it. They need their opium and they go and get their dose every weekend.
