"If you can just convince the dope people that the gun people are right and the gun people that the dope people are right, we could actually live in a lot more freedom."

“There Is No God" on This I Believe”

“The question I get asked by religious people all the time is, without God, what’s to stop me from raping all I want? And my answer is: I do rape all I want. And the amount I want is zero. And I do murder all I want, and the amount I want is zero. The fact that these people think that if they didn’t have this person watching over them that they would go on killing, raping rampages is the most self-damning thing I can imagine. I don't want to do that. Right now, without any god, I don't want to jump across this table and strangle you. I have no desire to strangle you. I have no desire to flip you over and rape you.”

“I can read ideas from all different people from all different cultures. Without God, we can agree on reality, and I can keep learning where I'm wrong. We can all keep adjusting, so we can really communicate. I don't travel in circles where people say, "I have faith, I believe this in my heart and nothing you can say or do can shake my faith." That's just a long-winded religious way to say, "shut up," or another two words that the FCC likes less.”
