120mm - What evidence do you have for your view that cultural difference (exemplified, I suppose, by internet pornography) is the principle reason for Islamist suicide attacks, as opposed to the reasons listed by Islamist terrorists in their numerous statements of purpose which almost exclusively reference politics?

One could make the argument that tribalism, the treatment of women as property, violence, etc. are far more prevalent in sub-Saharan Africa than in the Muslim Middle East. Yet we have a distinct lack of African terrorists. What accounts for this?
