Fundamentalist Islam is the same reaction to a perceived societal decay that we see from fundamentalist Christians in America.
When people view conflicts, contradictions, and uncomfortable changes in their society, it is human nature to search for reasons and to blame those who are responsible for such changes.
In many parts of the world, particularly in many Islamic communities, people see problems in their society and they blame their corrupt, Westernized government, their greedy business leaders, and the overall influence of the West. In such places, it is all too easy to blame the West, and America in particular, for the problems people see in their society. And so America, being the top dog of the West, represents, to such people, all that is bad in the modern world.
What is required for progress in this area is the realization that EVERY human being is capable of the most loving AND the most horrid gestures and choices. So while certain people are exhibiting extreme examples of beautiful or ugly behavior, it is all humanity. It is all us.
The people you are blaming and judging and vilifying are exhibiting HUMAN qualities. We are beautiful AND ugly. And we are capable of choosing either one.
That is what we are here to learn.
