Religion and its effects - Documentary BBC - A History of Syria (2013)

Just watch this. This region is complex, but how often do we hear this same thing - religious hatred fueling conflict.

Why? Because of two different religious leaders hundreds of years ago.
Because of a 700 year old bias against another group that "isn't really Muslem."

... If we get rid of religion, how many conflicts like this can we lower or eliminate completely?
