What is Islam? What makes someone a Muslim?
Stevenson dives into the characteristics of Islam (prophet, holy book, etc.) and the complexity of Jihad (struggle).
To most, Jihad is a struggle to fight the evil within oneself. Seems legit.
To others, Jihad is a Holy War against those who intend to suppress the religion. To them, if you are not a Muslim, you are in infidel, and you are one of those people. Woah...
It's complicated folks, and that's why we love it.
