Roberto Silva: Why? That is a general issue with the world.
I don't want to start a political discussion about today, but just for example, the Crusades were started because the Christian's felt that it is necessary to force their beliefs onto the non-believers. I am sure you can find current similar situations...

Half of the trouble in the world comes from people that think their ideas are so good that they have to force others to follow them. If not more.
