Let me give you some comfort - because I think you are deficient in maths. You say hundreds of millions out of 1.6 billion believe in violent acts - which equates to 200-300 mill minimum.
That's completely ridiculous!!!
but if you are unswayed by the above, I know of Christians/western democracies with populations far great than this number that have instigated wars and meddled in the political affairs of many countries resulting in violence and death to millions.
Do I need to mention them or do you get my gist.
