The Rational Response Squad (RRS) is an atheist activist group that confronts what it considers to be irrational claims[1] made by theists, particularly Christians.

[3] The challenge asks atheists to submit videos to the website YouTube, in which they record themselves blaspheming or denying the existence of the Holy Spirit.

[6] Magician Penn Jillette,[7] author Christopher Hitchens, philosopher Daniel Dennett, and Raëlism founder Raël participated in the project.

"[17] On September 16, 2007, Wired magazine reported that "YouTube had banned a group called the Rational Response Squad (RRS) after it complained its videos were being taken down due to spurious DMCA requests from" someone working on behalf of the Creation Science Evangelism ministry.

It further noted that while this highlights problems with DMCA, the ministry's own website said that "none of the materials ... are copyrighted, so feel free to copy these and distribute them freely.

[citation needed] Brian Sapient and Kelly O'Connor,[20] members of the RRS, participated in a debate with representatives from The Way of the Master, actor and evangelical Christian Kirk Cameron, and his colleague Ray Comfort, at Calvary Baptist Church in Manhattan on May 5, 2007.
