I talk about a Christianity that is enlightened enough to separate spirituality from the rest of life. Not just church and state, but knowledge and church.

You have to let individuals make their own choices and respect that, even if it's your own child. And that's what was taken away from me. My father passed away thinking I still had to go back to his way of believing.

My friend, the Dutch filmmaker Theo van Gogh, was murdered in 2004 for having been insufficiently reverent toward Islam.

I have had to pay a price for leaving Islam and for speaking out. I have to pay for round-the-clock security because of the death threats against me.

Every time I went on TV I got a threat.

Islam was like a mental cage. At first, when you open the door, the caged bird stays inside: it is frightened. It has internalized its imprisonment. It takes time for bird to escape, even after someone has opened the doors to its cage.

Muslim leaders should ask themselves what exactly their relationship is to a political movement that encourages young men to kill and maim on religious grounds.
