if the majority did i think the world would be in complete chaos by now. so to answer your question, no. because i am Muslim myself, and i know many other muslims who are very good people. i have yet to meet a very mean Muslim in person. i know there are mean ones in the world, but honestly, we are like everyone else.
I don't think any poll of Muslims worldwide has been done on that. However, available polls of Muslims have indeed shown a troubling tendency towards violence. For example, 65% of Palestinians support terrorism. This seems to be not uncharacteristic of many Islamic societies.
Those who have not been to Moslem countries or societies in non-Moslem countries, should really be careful drawing conclusions based on CNN and .... The truth is that the majority of any type of people in the world, just want some peace so they can go home and play with their children.
