Of course there are people who would like to eat breakfast without the screams of toddlers all around them, but those people should get over themselves and stop being stuck up and idiotic.

We have to understand how the extremists got the way they are. Without that kind of understanding, we'd never really get to know them. I put in nothing about their childhoods. But what I have put in is stuff about the weird symbiotic relationship between us and them.

At first, I did stories on people who were maybe just eccentric. Omar was a natural progression from that.

I have thought sometimes that the sanest people, the people who are just very balanced, very happy, are probably lower achieving than other people. My kind of irrationality happens to be fear or anxiety.

But when I was doing the KKK I had constant nightmares of being exposed as a Jew and lynched by the Klan.

But on the extremist side I didn't get any rejections at all. Everyone agreed to talk to me.
