Islam has grown in a troubled country, but how does that imply there's a casual relationship between Islam and poverty/social instability? This is like arguing the use of umbrellas causes the rain - how do your figures prove which part is the cause, and which part is the effect? Or if it's because of something(s) else entirely besides the rise in Islamic population?
