It's important to understand that violent Islam is only one face of violent religion.

One of the things about landays is that they thrive in a modern context. Early on I went to this incredible Pashtun novelist, Mustafa Salik, who is a bestselling novelist in Afghanistan and works for the BBC in Pashto. With the question of the sanctity of the poems in mind, I asked him, "Aren't you worried? They've been posted on Facebook and such." And he said, "Just the opposite. This is a folk form; they survive and thrive as people share them."

The power of the voice in rap is about the expression of truth, rather than the expression of some kind of artifice.

If we think about folk forms, they belong to disenfranchised people, people who have not been allowed access to the poetry of literature or the leisure time that comes with the pursuit of poetry. Instead, this is ceremony. This is a highly charged way to create a sacred space that isn't necessarily about God, but is about human experience at its most profound levels - whether that's love or grief, separation, or homeland. All are altered states.

I was examining what religious identity meant in Africa. Along the edge of the Islamic world, what patterns were shaping identity? And the truth is, when I looked at the rise of violent forms of religion, no single identity was prevalent. It's central to note that in Nigeria, that tree is rooted primarily in Christianity. It's not just Islamic militants in the Middle Belt.

In most of the world, poetry has such a different reputation than it does in Western culture.

In most of the world, poetry has such a different reputation than it does in Western culture. Poetry is a popular genre in Afghanistan. If you turned on the radio, there would be a poetry program that would be as popular as The Real Housewives. People aren't listening to poetry as if they're taking their vitamins. Instead, it's a popular vessel you can fill with anything. You could fill it with sass. You could fill it with rage. You could fill it with political statements.
