I am never going to write about dogs again. You can write about Islam, you can write about sexuality, but no, not dogs.

I think we're going to care more about Americans than Africans. I don't think that's ever going to go away, and I don't think it's ever going to go away that people care more about their families than strangers, and their communities over other communities.

I'm not a pacifist. I think the suffering of innocent people can be a catalyst for moral action. But empathy puts too much weight on the scale in favor of war. Empathy can really lead to violence.
