The Nightline Face-Off

What's wrong with God? "What's wrong with the tooth fairy?" asks Brian. "There's nothing wrong with something that most likely doesn't exist."

"Atheists are completely vilified. And it's OK," says Kelly, an atheist who works alongside Brian and also asks that her last name not be used.

"It's actually OK to hate atheists," Kelly says. "We are like the last group that people overwhelmingly agree it's OK to hate, because there's an absurd caricature of atheism out there."

While their theological views differ from the Way of the Master, their approaches are similar -- brash and in-your-face. The Rational Response Squad challenges people to take the Blasphemy Challenge in which they make videos of themselves denouncing or blaspheming the Holy Spirit, and then post them on YouTube.

One of the posts is by a young-looking man named Chandler. He says, "I've come to the conclusion that alongside the fact that there is no Santa Claus and there is no Easter bunny, there is also no God. So, without further ado, my name is Chandler and I deny the existence of the Holy Spirit."

Taking risks with your own soul is one thing, but the Rational Response Squad advertises for the Blasphemy Challenge on Web sites for teens, such as Tiger Beat (tigerbeatmag.com).

"They have already been targeted," Brian says. "So hopefully, they are at a point where they are not so indoctrinated and set in their ways that they can overcome this religious superstition that has been put into their brain unfairly."

At the end of the "Nightline" segment, Brian Sapient says, "If they [the Christians] want to come to the table and present their evidence, I will present my evidence. And we will see how much of theirs is based on faith, and how much of mine is based on fact."

The Face-Off

Ray Comfort saw the piece on the Blasphemy Challenge and he immediately e-mailed "Nightline" to say that "We would like to challenge them to a public debate. … Let's hear their best evidence as to why God doesn't exist, and let the audience decide whose evidence is based on faith and whose is based on fact. We cannot only prove that God exists, but we can prove that the atheist doesn't."
