muslim countries don't tend to be very violent, apart from those that have been "liberated" by the west into states of anarchy. take indonesia, largest concentration of muslims on the planet, 250 mill population , 87% muslim and one the world's very lowest murder rates
And yet last year, 82% of all terrorist attacks occurred in just 5 Muslim majority countries. HHMMM !!!
According to the GPI (Global Peace Index,), the ten most peaceful countries, in order, from 2013 to 2014 were:
Iceland, Denmark, Austria, New Zealand, Switzerland, Finland, Canada, Japan, Belgium, and Norway.
The most violent countries were Syria, Afghanistan, South Sudan, Iraq, Somalia, Sudan, Central African Republic, Democratic Republic of the Congo, Pakistan
See the connection yet !!!
Here I will help you, 7 of the 9 most violent countries in the world are Muslim Majority countries 10 of 10 of the most peaceful countries in the world are non-muslim countries.
Hope this helps.
