It is very difficult to argue with what she wrote, but we must understand that the practice of Islam in West Africa is not monolithic, and that adherence to a particular brand of Islam or Christian is linked to tribal affiliation.

Boko Haram is being described as a "Northern Nigerian" phenomena, it is really a Hausa-Fulani/Kanuri phenomena largely limited to the parts of Nigeria where Hausa is the lingua franca.

This is why Kenya, Nigeria and most of West Africa are different from Somalia. Kenya's Islamists are more likely to be ethnic Somalis or from the Mombasa area. That makes them easier to isolate and presents us with the terrifying prospect of massive retaliation attacks by the majority Christian tribes in Kenya, should the situation get out of hand.
