In her second to last paragraph the author gets to the point. Why does violence appeal to a select group of Muslims? The answer to that question is obvious if you make some comparisons with history and look at the Koran itself. For the author to ask the question implies she is blind to the obvious.

Any state, culture or movement that is founded on strict adherence to a set of behaviours has a hard time shifting gears once it matures and takes on a different character. Islam was originally founded in a desert area by nomadic peoples, not the sedentary cultures of today.

The Koran encourages violence in many ways, like allowing men to beat their wives. It  encourages Muslims to stike out against non Muslims.  All very good 1500 years ago but maybe not today. Yet Muslims of today still take guidance from this holy book, created so long ago.

I should hope that during Ramadan the author will set asside wishful thinking and reflect on this connundrum.
